CMT Scores and Teacher Evaluations – But Wait – That’s Like Comparing Apples and Tomatoes

Governor Malloy, Education Commissioner Stefan Pryor and the rest of the “education reformers” continue to claim that Connecticut needs a “one-size-fits-all” approach to teacher evaluations in which teachers are, at least in part, rewarded, promoted or let go based on how well their students do in Connecticut’s standardized tests.
Malloy, now famous for his -” I’d don’t mind if they teach to the test as long as the test scores go up” – statement has been leading the mob mentality that is claiming that it is imperative that 20-40% of a teacher’s annual evaluation be based on their student’s annual test scores.
What is never articulated is what counts as a “good” or a “bad” change in test scores.
Thinking of the following example as if it was a question on a standardized test;
Teacher A is a 4th grade teacher in New Britain. This year, 25.7 percent of teacher A’s class scored “at goal” on the Connecticut Mastery Test in reading (up from 22 percent last year).
Teacher B is a 4th grade teacher in Hamden. This year, 56 percent of teacher B’s class scored “at goal” in the CMT in reading (up from 54 percent last year).
Teacher C is a 4th grade teacher in Fairfield. This year 78 percent of teacher C’s class scored “at goal” in the CMT in reading (down from 79 percent last year).
Presently, in New Britain, 22 percent of 4th graders are at goal in reading and 27 percent are at goal in math. On the other hand, in Hamden, where poverty and language barriers are not as great as in New Britain, 54 percent of 4th graders are at goal in reading and 58 percent are at goal in math. Finally, in Fairfield, 79 percent of 4th graders are at goal in reading and 84 percent are at goal in Math.
Do any of the three teachers deserve a merit bonus? Do any of the teachers need some extra professional development support? Do any of the teachers need to be put on the “watch list” for unsatisfactory performance?
If the number of students testing a goal is going up – is that a sign of the teacher’s success? If a teacher maintains test scores is that good or bad? What about a teacher whose sees the number of students testing at goal actually drop?
In this case, the New Britain teacher saw a 15 percent increase in the number of students testing at goal, the Hamden teacher had a 5 percent increase and the Fairfield teacher saw a slight decline. Which teacher is succeeding? Which is failing?
Of course, without knowing the total number of students taking the test in each class we can’t even be sure the information is statistically significant. It may be that in all three situations the change is within the standard margin of error and therefore no conclusion can be reached in any of the cases.
Meanwhile, what would we do if one 4th grade class in Meriden has a 7 percent drop in the number of Latino students and sees a 5 percent increase in the number of students at CMT goal, while the same sized class in an elementary school across town has a 10 percent increase in the number of Latino students and the number at goal in that class drops by 2 percent? Which teacher has done a better job?
These are very real issues. In New York, the failure to account for these issues has destroyed the entire credibility of their new teacher evaluation effort.
But don’t let the details stand in the way of progress.
While the “reformers” continue to yap about the need to link test scores to teacher evaluations, they still haven’t begun to articulate how including standardized test scores in teacher evaluations are going to help determine who gets a bonus in pay or who gets punished.
What is clear is that among those who profess to know that attaching test scores to teacher evaluations is definitely the way to go is the Connecticut Association of Public School Superintendents.
The spokesperson for the Superintendents has repeatedly joined in Malloy’s claim that teachers must be held accountable for their students standardized test scores — despite the fact that test scores are driven by wide range of factors far beyond the teachers’ control.
The logically absurd claims being made by the superintendents, and other reformers, got me wondering about how they could consistently get away with comparing apples and tomatoes without ever admitting that the comparison is fundamentally bogus.
Then again, maybe they are on to something…
These superintendents are paid big bucks to run their local school systems.
True they are supporting legislation that undermines the rights of their own boards of education, local elected officials and taxpayers but they must know what they are doing. They are all certified to be superintendents (well all but one).
So, perhaps this whole apple vs. tomato approach might also serve as a useful mechanism to judge the effectiveness of Connecticut’s superintendents
Let’s look at the data.
The following chart shows what taxpayers are getting for the money they pay superintendents.
The data measures the superintendents’ cost per student, their cost per school employee, their cost per poor student (that is students who receive free or subsidized lunches) and the cost per students who don’t speak English.
We might say that it is a good way to determine how superintendents are allocating their resources. There will certainly be differences from town to town, but the fundamental cost per unit has to be somewhat similar, right?
Like mastery tests, these costs per unit measurements will provide the state (and taxpayers) with an opportunity to determine which superintendents are doing well and should be rewarded for their efficient operation of services, which need a dose of professional development to help them get a hold of their financial operation and which need to be removed for their failure to get their job done correctly.
The data tells us;
- A superintendents’ cost per student ranges from a low of $9 in Waterbury and $11 in Hartford to a high of $85 in Weston and $62 in Wilton.
- A superintendents’ cost per school employee ranges from $60 in Waterbury and $73 in Hartford to $537 in Wilton and $463 in Brookfield.
- A superintendents’ cost per low-income student ranges from $11 in Hartford and $12 in Bridgeport to $6,396 in Weston and $5,831 in Wilton and.
- And a superintendent’s cost per non-English Speaking Student ranges from $61 in Hartford and $87 in Waterbury to $16,071 in Darien and $13,591 in Weston.

Now, while it is true that all this may be comparing apples and tomatoes, certainly there is validity in the saying that what’s good for the goose should be good for the gander.
If teacher evaluations are going to be dependent, at least in part, on standardized test scores, then certainly superintendent evaluation should be dependent, at least in part, on how well they do handling standardized per unit expenditures.
Let’s face it, are you really telling me that the Darien superintendent should be spending $16,000 for a student who doesn’t know English when Hartford is only spending $61?
