Problems with the use of student test scores to evaluate teachers. By Eva L. Baker, Paul E. Barton, Linda Darling Hammond, Edward Haertel, Helen F. Ladd, Robert L.

Yet in practice, American public schools generally do a poor job of systematically developing and evaluating teachers. How The Best Leaders Lead Brian Tracy Pdf Goals' title='How The Best Leaders Lead Brian Tracy Pdf Goals' />Many policy makers have recently come to believe that this failure can be remedied by calculating the improvement in students scores on standardized tests in mathematics and reading, and then relying heavily on these calculations to evaluate, reward, and remove the teachers of these tested students. While there are good reasons for concern about the current system of teacher evaluation, there are also good reasons to be concerned about claims that measuring teachers effectiveness largely by student test scores will lead to improved student achievement. If new laws or policies specifically require that teachers be fired if their students test scores do not rise by a certain amount, then more teachers might well be terminated than is now the case. But there is not strong evidence to indicate either that the departing teachers would actually be the weakest teachers, or that the departing teachers would be replaced by more effective ones. There is also little or no evidence for the claim that teachers will be more motivated to improve student learning if teachers are evaluated or monetarily rewarded for student test score gains.

Some states are now considering plans that would give as much as 5. Based on the evidence, we consider this unwise. Any sound evaluation will necessarily involve a balancing of many factors that provide a more accurate view of what teachers in fact do in the classroom and how that contributes to student learning. Evidence about the use of test scores to evaluate teachers. Recent statistical advances have made it possible to look at student achievement gains after adjusting for some student and school characteristics.

These approaches that measure growth using value added modeling VAM are fairer comparisons of teachers than judgments based on their students test scores at a single point in time or comparisons of student cohorts that involve different students at two points in time. VAM methods have also contributed to stronger analyses of school progress, program influences, and the validity of evaluation methods than were previously possible.

Nonetheless, there is broad agreement among statisticians, psychometricians, and economists that student test scores alone are not sufficiently reliable and valid indicators of teacher effectiveness to be used in high stakes personnel decisions, even when the most sophisticated statistical applications such as value added modeling are employed. For a variety of reasons, analyses of VAM results have led researchers to doubt whether the methodology can accurately identify more and less effective teachers. VAM estimates have proven to be unstable across statistical models, years, and classes that teachers teach. One study found that across five large urban districts, among teachers who were ranked in the top 2. Another found that teachers effectiveness ratings in one year could only predict from 4 to 1. Thus, a teacher who appears to be very ineffective in one year might have a dramatically different result the following year. The same dramatic fluctuations were found for teachers ranked at the bottom in the first year of analysis. This runs counter to most peoples notions that the true quality of a teacher is likely to change very little over time and raises questions about whether what is measured is largely a teacher effect or the effect of a wide variety of other factors. A study designed to test this question used VAM methods to assign effects to teachers after controlling for other factors, but applied the model backwards to see if credible results were obtained. Surprisingly, it found that students fifth grade teachers were good predictors of their fourth grade test scores. Inasmuch as a students later fifth grade teacher cannot possibly have influenced that students fourth grade performance, this curious result can only mean that VAM results are based on factors other than teachers actual effectiveness. VAMs instability can result from differences in the characteristics of students assigned to particular teachers in a particular year, from small samples of students made even less representative in schools serving disadvantaged students by high rates of student mobility, from other influences on student learning both inside and outside school, and from tests that are poorly lined up with the curriculum teachers are expected to cover, or that do not measure the full range of achievement of students in the class. For these and other reasons, the research community has cautioned against the heavy reliance on test scores, even when sophisticated VAM methods are used, for high stakes decisions such as pay, evaluation, or tenure. For instance, the Board on Testing and Assessment of the National Research Council of the National Academy of Sciences stated,VAM estimates of teacher effectiveness should not be used to make operational decisions because such estimates are far too unstable to be considered fair or reliable. A review of VAM research from the Educational Testing Services Policy Information Center concluded,VAM results should not serve as the sole or principal basis for making consequential decisions about teachers. There are many pitfalls to making causal attributions of teacher effectiveness on the basis of the kinds of data available from typical school districts. We still lack sufficient understanding of how seriously the different technical problems threaten the validity of such interpretations. And RAND Corporation researchers reported that,The estimates from VAM modeling of achievement will often be too imprecise to support some of the desired inferencesand that. The research base is currently insufficient to support the use of VAM for high stakes decisions about individual teachers or schools. Factors that influence student test score gains attributed to individual teachers. A number of factors have been found to have strong influences on student learning gains, aside from the teachers to whom their scores would be attached. These include the influences of students other teachersboth previous teachers and, in secondary schools, current teachers of other subjectsas well as tutors or instructional specialists, who have been found often to have very large influences on achievement gains. These factors also include school conditionssuch as the quality of curriculum materials, specialist or tutoring supports, class size, and other factors that affect learning. Schools that have adopted pull out, team teaching, or block scheduling practices will only inaccurately be able to isolate individual teacher effects for evaluation, pay, or disciplinary purposes.
