The challenges of promoting Equal Access to quality teachers
5 min readBy Morris Mabior Awikjokdit
The start of a school year brings with it a crop of anxious parents hoping their child has an excellent teacher. And recently, policymakers have wondered whether the playing field is level when it comes to getting that excellent teacher. Education managers must ensure that “family income and race still too often predict how likely a child is to attend a school staffed by great educators.” Beginning in April next year 2015, states will need to submit plans to the National Ministry of Education to ensure that “poor and minority children are not taught at higher rates than other children by inexperienced, unqualified, or out-of-field teachers.
On the surface, this is a reasonable response to the issue of inequity in access to quality teachers. But how large of a problem is teacher inequity really? Looking at recent analysis and research on teacher equity suggests two conclusions. If equity is defined as access to teachers with particular characteristics such as experience, the problem seems large. But if equity is defined as access to effective teachers, those that contribute more to test score growth, the problem does not seem large. This is not to say issues of teacher equity should be ignored, but that proposed solutions should be proportional to the problem.
One proxy for effectiveness is experience, as the ministry of Education’s statement notes. What kinds of students are taught by inexperienced teachers? Minority enrollment is not as accurate a predictor of achievement as disadvantage, however. With Ellie Klein’s assistance, I looked at the relationship between teacher experience and disadvantage from the 2011 Schools and Staffing Survey, a nationally representative survey of teachers conducted by the National Center for Annual Education Statistics. These data show that a bit more than 50 percent of inexperienced teachers (those with less than four years of experience) are teaching in high-poverty schools. In contrast, 19 percent of inexperienced teachers are teaching in affluent schools.
That’s a big difference. An inexperienced teacher is nearly three times more likely to be in a high-poverty school than in an affluent school. And the inequity appears to be getting more pronounced. In 2007, according to the same AEC and EMIS data source, about a third of inexperienced teachers were teaching in high-poverty schools and about a third were teaching in affluent schools.
But an even better proxy for teacher quality is effectiveness, a teacher’s ability to move students ahead on tests. Assigning disadvantaged students to weak experienced teachers rather than to strong inexperienced teachers does not tackle the underlying equity issue.
To get a sense of the magnitude of teacher inequity viewed through the lens of effectiveness, we need to measure effectiveness in some way. Suppose we measure it as “value-added,” using a statistical model to attribute to teachers an amount of test-score growth shown by their students during the year. If two teachers had similar students at the start of a school year, the one whose students have higher test scores in the spring will have higher value-added. There is lots of debate about these models, but they are appealing as a uniform approach for measuring the vague concept of teacher quality. (As an aside, calls to reduce the frequency of testing, such as here and there. Not having annual testing means student growth can no longer be measured, which means forgoing efforts to assess effects of policies to spur student growth.)
The Institute of Education Sciences funded three studies of the teacher-quality issue, using value-added models and measures of student and school poverty. The studies included thousands of teachers and tens of thousands of students in a wide range of states and counties. Because value-added measures rely on annual test scores, the studies report results for teachers from fourth to eighth grades, the grades for which annual tests are required. Results from two studies are discussed here and the third study had consistent findings.
In the poorest primary schools, 19 percent of teachers were high performers. Equity would mean 20 percent of teachers would be high-performers regardless of a school’s poverty level. So, there is evidence of some inequity, though it is not overwhelming.
Gaps were larger in middle schools. In the most affluent middle schools, 32 percent of English and language arts teachers were high performers. In the poorest 20 percent of middle schools, 12 percent of English and language arts teachers were high performers (the differences were smaller in math). These gaps varied widely between county with some county having larger gaps and others having none at all.
Another study focused on the match between disadvantaged students (not schools) and effective teachers. It showed that the “effectiveness gap” is small. The overall score gap between disadvantaged and advantaged students was 28 percentile points in reading. That’s a big gap. The study showed that distributing students equitably among teachers would reduce this gap to 26 percentile points (in math, the study estimated that a 26 percentile-point gap would be reduced to 24 points). A closer look found that differences were larger in some districts and near zero in others.
Using this evidence, an ideal policy guaranteeing students equitable access to effective teachers could reduce a small amount of the achievement gap (about seven percent of it, the 2-point reduction divided by the 28-point base).The actual effect would likely be smaller. The effect also relates only to narrowing the gap. It’s hard to predict what will happen to overall achievement. It could go up or down.
