That old sorcerer has vanished
And for once has gone away!
Spirits called by him, now banished,
My commands shall soon obey.

In Goethe's classic, the apprentice uses a sorcerer's spell to ease his daily chores. Chanting the master's words, he brings a broomstick to life and tells it to fetch water to clean the workshop. The broomstick obeys, only too well. It races between the well and back until the workshop begins to flood. Although the apprentice had enough knowledge to set magic in motion, he could not think ahead to what he did not know.

I worry about a similar flood of unintended consequences if the Los Angeles Times moves forward with its plans to publish a database that places 6,000 Los Angeles third- to fifth-grade teachers on a spectrum from "least effective" to "most effective." The Times believes that the data will be a powerful tool to force better teaching, but it cannot anticipate all of the consequences. For example, consider that capable prospective teachers might avoid a profession in which they risk public embarrassment based on an undeveloped science. Consider the well-documented estimates that 25% of the value-added assessments are likely to be in error.

Publishing the database might easily undermine parent and teacher morale and make it more difficult for principals to advance school improvement. Being told that their child's teacher is "ineffective," or even marginally less effective than a teacher across the hall, may lead some parents to pressure the principal to place their child with a "high-scoring" teacher. Pitting parents against one another or against their principal is not a recipe for school improvement.

The Times' teacher effectiveness rankings are based on an elaborate statistical model created by Richard Buddin, a senior economist and education researcher at the Rand Corporation. (Significantly, Buddin did not attach teachers' names to his analysis; that was done by the Times.)

Buddin is one of many researchers across the country exploring so-called value-added approaches to assessing teacher quality. The assessments measure gains that students make on standardized tests from one year to the next. For example, researchers compare test scores of fourth graders with their scores as third graders to determine the "value added" by the fourth grade teacher. Proponents believe that the "value added" reliably distinguishes between more and less effective teachers. And they think that school officials would use such comparisons to target support to struggling teachers and motivate them to do better.

Yet value-added analyses focus narrowly on standardized tests, usually in math and English Language Arts. These tests give important information about student learning, but they ignore much learning that matters to students, parents, and teachers. That's why it can be a useful tool, but cannot possibly stand alone as a measure of "effectiveness." The National Academy of Sciences has identified several of the problems posed by value-added methods. These cautions should be taken seriously.

  • First, student assignments to schools and classrooms are rarely random. As a consequence it is not possible to definitively determine whether higher or lower students test scores result from teacher effectiveness or are an artifact of how students are distributed.
  • Second, it is difficult to compare growth of struggling students with the growth of high performers. In technical terms, standardized tests do not form equal interval scales. Enabling students to move from the 20th percentile to the 30th is not the same as helping students move from the 80th to the 90th percentile. These test score numbers are not like inches along a tape measure that have the same value regardless of where they occur.
  • Third, estimates of teacher effectiveness can range widely from year to year. In recent studies, 10-15% of teachers in the lowest category of effectiveness one year moved to the highest category the following year while 10-15% of teachers in the highest category fell to the lowest tier.


The National Academy of Sciences concluded that value-added analysis "should not be used as the sole or primary basis for making operational decisions because the extent to which the measures reflect the contribution of teachers themselves, rather than other factors, is not understood."

And yet, the Los Angeles Times is about to publish a database with the teacher effectiveness rankings of 6,000 elementary school teachers. The Times argues that its role is to provide "parents and the public ... information that would otherwise be withheld" about the "performance of public employees." The Times should not believe in the magic of this data, and should realize that it cannot foresee or control all of the consequences.

Secretary Duncan said in a June 2009 speech, “Just as the American Bar Association polices the legal community and the AMA (American Medical Association) does the same for the medical profession, you must get more serious about accountability.†What are the ramifications of this statement? One can imagine that in the last few years many lawyers working as LA public defenders have handled cases that did not have optimum outcomes. Should we publish the names of these public defenders? How about doctors with similar outcomes handling alcohol and drug cases---publish their names? If the community did not want suffer some high legal cost down the line it would be advisable to proceed with caution when publishing the names of lawyers or doctors.
Michelle Rhee, Chancellor of D. C. Public Schools, has recently fired a number of teachers which her system has determined to be “ineffective.†If we are following the guidance of the ABA and the AMA we can assume that provisions are being made for the appropriate teacher’s professional organization to hold hearing in these cases. Naturally, if these teachers are
shown to be ineffective their teaching certificates should be immediately rescinded. We would not want ineffective teachers anywhere in the system. Using the ABA/AMA model we would assume that a formal hearing has been held for each teacher involved, the applicable teaching certificates have been revoked, and that there is an appropriate appeal procedure (I would be surprised if this is the case).

Value-added is just another example of our fixation with a "magic bullet" solution. Test scores can be part of the answer. They can track teacher effectiveness to some extent if properly analyzed for some of the effects outlined above, especially over time.

But I think the use of tests to evaluate students or teachers leads to teaching to the test, not real teaching and not real learning.

Teach teachers better to begin with. Don't have coaches with teaching degrees in PE teach math. Make teachers work longer to achieve tenure. Make teaching an honorable profession with appropriate pay and working conditions. Everyone talks about learning in a bad school with limited materials, but teachers have to teach in these conditions too. In CA a recent news report stated that, on average, California teachers spend about $1000.00 a year on basic supplies for their students. This type of thing is ridiculous.

I spent a lot of time when my kids were in school arguing with bad teachers and deaf administrators but at the same time, value-added is no solution and race to the top is worse than useless.

Where is social promotion in the discussion of teacher competency? If a single-subject secondary credentialed teacher is given students in middle school and beyond that are 5 years or more behind, what is this single-subject credentialed teacher with no remedial language skills supposed to do to address these students needs, while also being obligated to teach a substantive course? What part of my body am I supposed to point to explain the concept of democracy to a student that has a 500 word working vocabulary? Nobody disagrees with the assumption that there are some pretty awful teachers out there. Maybe this is because of the 50% turnover of teachers within 5 years given the intolerable behavior and total unwillingness of LAUSD administration to address the subjective needs of the students or maintain minimum discipline, which might impact ADA revenue from the State of California. Why scapegoat teachers for the incompetent and possibly criminal malfeasance in the operation of LAUSD by a self-serving bureaucracy.
Ironically, as I wait to have my name submitted to the LAUSD Board for dismissal as a teacher, I am painfully aware that teacher accountability will not be used to get rid of bad teachers who go along with LAUSD institutional incompetence, but rather good teachers that try to teach all students at the highest level. At www.perdaily.com we try and talk about what is really going on in public education and how to fix it. Interested?

I am absolutely against publicizing the names of the teachers who are doing well and poorly, for many of the reasons discussed in the article. However, the school administration should be pressured to know this information and to do something about it. That something shouldn't be firing the teachers (except as a last resort) but, to start with, let the teachers who are effective demonstrate or coach the less effective teachers. And, although standardized tests aren't everything, they do measure very important skills, and knowledge students must have to progress. The Times did a service in comparing like-for-like, and in pointing out that neither principals nor LAUSD are using this to improve teaching.

I think John Rogers wrote an excellent article on the "Value Added" subject. He touched upon many of the questions I have thought about. I'm happy that I am retired from teaching and don't have to put up with this nonsense.

I was considered by administrators, parents, fellow teachers, and students as a good elementary teacher. (Forgive my apparent lack of modesty. I am trying to make a point.) In this new "plan", my evaluation could be considered very good in one year and lousy in the next year. Did my abilities change? I don't think so. What does change are factors the teacher has no control over. To name a few-- high student turnover throughout the year, poor parent interest and support, high number of discipline problems, and high number of special education students.

In those difficult years, I actually worked harder. Some of my successes were huge in terms of student attitudes and developing self confidence. I felt very good about their overall progress. However, none of this can be measured. I would be considered a poor teacher under the new plan.

What is forgotten by those who have never spent any real time in a classroom, is that students are not "widgets". They are human beings of infinite variety. Finally, when will "they" learn that not everything can be measured?

This is why I am at the end of a decades-long teaching career; I am tired of being blamed, punished, furloughed, and used as a political football, when in reality, I don't see anyone but teachers really giving a rat's behind about children.

What is so maddening about this debate is the reductionism taking place. This is not a debate about whether or not teachers should be evaluated. This is about the fact that the application of an economic analysis to the evaluation of teacher efficacy is, at best, untested. In the immediate, this is about 1) the independent decision by the Los Angeles Times to use VAA in a (potentially dangerous) way for which it was not originally intended and 2) the Los Angeles Unified School District using the hype around this issue to push the use of yearly VAA into yearly teacher evaluations.

Reducing this argument to a shouting match between "unions trying to protect bad teachers" and "pro-business model policy wonks pushing testing as the be all to end all" helps no one, least of all the students and parents being served by LAUSD.

How stupid is it to complain about poor quality teachers and then make the job so freaking miserable and demoralizing that no one with an ounce of brains and any other options will consider taking it? That's what this type of hostile, We blame YOU for everything wrong in our society, stance does. I had great teachers growing up (70s) and none of them were treated this way. They were proud of their profession and treated with respect by my parents. My parents did not need to blame the teachers because THEY were doing their jobs as parents.

I wanted to be a teacher but chose to become a computer programmer when I saw how little money and respect teachers were getting. They are the whipping boy for everything wrong in our society. Hey parents, TURN OFF THE TV.! Read to your children!

My kids did great in school but my husband and I allowed them very little television viewing time and no video games before age 12. We also bought them any books they wanted, and I read to them every night until they were 9 or 10 and wanted to read to themselves before bed. The idea that the teacher should be blamed for an unmotivated, un-parented child's test performance is ridiculous. . And, if you really want to publish the teacher's effectiveness ranking, I say, publish the names of the parents of low test scorers as well. That would be the fair thing to do.
09:00 PM on 08/24/2010
Well said Kate, publish names of parents who do not attend meetings, who drop off their children at school at 6 am and pick them up at 6 pm, or bring them in an hour late every day, parents who never take their children to the library, publish their names alongside their child's test scores and you'll see a correlation between low test scores and parent involvement. The L.A. Times is a joke, they hate Duffy and so they publish this cr a p, why don't they publish all of LA county's test scores for ALL districts?

Jason Song is at the core of all these anti-teacher articles the LAT has printed for the past several years. One wonders what exactly happened to him back in school.
02:22 AM on 08/25/2010
Yep. I have a friend who teaches high school, and he tells me that he CAN'T give low grades to students who deserve them, because he would be fired. He says he is not allowed to give students failing grades. He has students who just don't do their homework at all, and he has to pass them on through the system. It seems to me that the people not being held accountable are the students and parents.

I remember a time when teachers welcomed the Value Added Assessment because it provided a fairer measure of student success. The student entering 5th grade (under a standard achievement test measure) for example, would be expected to leave 5th grade reading at a 6th grade level - even if they entered the 5th grade reading at a 3rd grade level. Using VAA, the teacher would be given credit for each year of instruction - so if the same student left 5th grade reading at a 4th grade level, the teacher still received "credit where credit was due" for bringing that student along one full year. Similarly, if a student entered 5th grade already reading at a 5th grade level and then finished 5th grade still reading at a 5th grade level - no learning gain had been achieved.

All measures have their flaws - it's that way in the private sector as well - that doesn't mean all measures are meaningless or can be easily discounted. I personally welcome the VAA as one of many tools we can use to measure teacher effectiveness and the opportunity it brings us to tailor or differentiate the lessons to meet the needs of each student.

Teachers ought to be constantly tested, monitored and graded against both their peers and standards.

Unintended consequences? Geez. LA just spent $578 Million on ONE school for 4200 kids, in a district with a 50% dropout rate.

We had BETTER be testing and grading.

Sure... it's all the teacher. It couldn't possibly be malnourished, poorly clothes, attention deficit, unruly, disrespectful, out of control, potentially physically violent students with absentee, apathetic and litigious parents now could it. One individual, who's job is dependent on the success of each student in overcrowded, underfunded classrooms and schools, while working hundreds of hours of overtime, after years of continued additional education all for less than the median salary while they spend hundreds of dollars out of pocket to provide basic materials. You obviously have never been a teacher, know a teacher or have talked to a teacher.

I guess all I can say about that is the schools shouldn't have systematically usurped parental authority over the years and become an instututional pusher for big pharma - Ritalin. All a kid has to do is tell the school psychobabbler that "dad hit me" and all hell breaks loose. You cower parents and then blame what happens in school on them, not that parents have even the smallest bit of say about school policy. The schools have become an addict creating, agenda pushing arm of the police department and you wonder why it's all chaos?

Great blog. The reality is that our failing educational system may be the biggest threat facing our country and it is unfortunate that for the past 10 years, the administrations (first Bush II and now remarkably Obama) have been going about addressing this problem in the wrong way. The adoption of these teacher performance measures as you suggest are at best bad science and at worst a tool that will further exacerbate the problem. Instead of focusing on measures first and root cause analysis second, the administration and the Department of Ed should be trying to find the root of the problems and then addressing these. They should first look at the research of Wilkinson and Pickett and discover how the inequalities that have been growing for the last 30 years in the US are integrally linked to the falling outcomes in education. They should also consider exploring how the SCOTUS ruling that education is not a fundamental right has damaged the system. They should explore how this has led to the underfunding of students who most need the highest level of funding and support and the complete waste of money that has been pushed to those schools and the students that already have a marked economic advantage. Only once we address these vast inequalities both in society at large and then between the different school districts will we ever be able to begin to really address the problems with the education system.

Yeah, it's all the teacher's faults, forget the low pay,budget cuts,terrible parents that only show up when the student is in trouble if they're there at all, failed levies and society at large...let's blame the teachers for all the failings of our children, that way we won't have to take any responsibility.

Such an argument always reads to me "We have to protect the jobs of teachers, because ultimately those jobs are irrelevant in the larger picture of a child's education."

I don't mean to downplay parental involvement at all, but just that a comment that attempts to alleviate teachers from any responsibility for the failures in their classroom would also preclude them from taking credit for the stories of success.
05:54 PM on 08/24/2010
Agreed,although I didn't go that far, of course teachers need to be accountable, but at the same time, walk a mile in their shoes ( inner city) and see what they have to work with...some schools are war zones, teachers buy many of their own supplies and often work overtime...and then to deal with dangerous or spoiled rotten kids that have more rights than they do.

School budgets are being cut across the nation. Class sizes have been raised to levels unseen for decades. Teachers and administrators have been laid off, transferred, or demoted. Teachers and administrators have had their pay cut and assigned furlough days. Students are having a more difficult time getting the instruction they need, the classes they need, counseling and the support services, not to mention programs in art, music, athletics and other activities which make school meaningful. It is in this environment that pundits and politicians propose to make standardized tests all important. It’s not hard to see why. Because you can focus on tests and try to pretend that budgets aren’t being cut, class sizes rising, art and enrichment programs being cut, counseling and support services slashed. Budgets won’t have to be replaced, teachers won’t have to be hired, programs won’t have to be reconstructed—no, we’ll just scapegoat teachers and administrators alike—everyone who has direct connection to the actual student.

This championing of standardized test scores as a cure-all in education (while simultaneously agreeing to slashing every other aspect of education) is not just erroneous, it’s fundamentally duplicitous and unfair. Finally, it is students who will be punished and dunned with these endless standardized tests, the boring curriculum that will be tailored to the tests, and the substandard schools which will continue to languish without educational programs that are actually meaningful to students. But, of course, Skelton and the test champions will never have to face the kids.

Then how do we asses Teacher effectiveness? If we can't test the Teachers, the students and the curriculum then maybe it is time we take the "public" out of public education. We must be able to weed out the Teachers that are not doing a good job, of which there are many. because of unions and tenure many teachers are gaming the system as others do in other jobs. Being a Teacher at one time was a calling, now, in some cases, not all, it is no longer seen as that. All you have to do is look at the inequality of Teacher's pay across the country. Private schools are able to pay much more than public schools.Public schools have turned into promoting the athlete more than a straight A student. Athletics bring in a whole different dynamic of raising money for their schools.

As with any job the employee is graded on different aspects of their performance .This should be no different for Teachers, especially since they are in charge of our most precious commodities.

Assessing the Administrative portion of schools and the Superintendents role should looked at more than the Teachers. I know of many school where the Administrators and the Superintendents salaries rival those of big business. Many make over 6 figures. Is Education a business or should it be an investment in our future.

Study after study has shown that the most important factor in the successful education of a child is parent involvement; Not degrees, licenses, certifications, or pomposity, but parents who know their children and actively work on their learning environment.
