Project STAR researchers concluded that adding a teacher's aid to a regular
size classroom doesn't affect test scores. Cutting class size does affect
test scores. Perhaps the district's class size reduction program didn't
improve test scores in most of the high poverty schools because it was
abandoned in most of those schools.
On the other hand, the district had at least a couple of model, high poverty
schools, including North Star elementary, which, a few years ago, posted
scores on academic achievement tests above the district average. North Star
reportedly reduced its average K-3 class size to below the districtwide goal
of 19. Reports to the board suggested that most of the North Star teachers
were likely to stay put for a while.
Aside from the direct benefits of small class sizes, there appear to be
indirect benefits, such as a lower rate of teacher turnover, which reduces the
concentration of inexperienced teachers over time.

Did the researchers offer any explanation for why students seemed to do
better in math classes taught by teachers of the same race? Who did this
later analysis? Who funded it? Where can one locate it? Why is it
significant? What are the policy implications?

It is true that one cannot expect to replicate the results of a study if one
does not replicate the conditions under which it was conducted. However, the
district claims that high poverty schools have the option of replicating
The district achieved an average of 19.5 students per K-3 classroom in the
1994-1995 school year. It was a little closer to 19 by 1999. However, the
average class size for high poverty schools increased during the period from
High-poverty schools are getting compensatory money, and many high poverty
schools are using that money to buy down class sizes, according to Catherine
Shreves, who cites Lincoln Elementary School as an example of a high poverty
school that uses compensatory money to buy down class sizes and is "beating
the odds" ([Mpls] Re: K-12 Schools; 31 October 2001).

Any strategy to boost student achievement employed by the district
will be of dubious value to students who are not continuously enrolled in the
district. The stability argument can be used against any and all strategies
the district might employ.
I'm sure that there are highly mobile students in the state of Tennessee,
including some who were followed in the Project STAR study. The presence of
mobile students didn't prevent students who were continuously enrolled in
small class rooms from reaping the benefits of small class sizes.

In order to reduce class sizes, one not only pays more for teachers salaries,
one also has to pay for more classrooms. What did the board do with the
money it had for more class rooms? If some of the money needed to carry
out the class size reduction program was used for other purposes, that money
The alternatives to class size reduction used in most of the high
poverty schools are clearly less effective as a means to improve student
performance. By sticking with policies that do not improve student
achievement, and rejecting policies that do, the board is certainly acting in
an irresponsible and unethical manner. The board is carrying out policies
that benefit one class of students at the expense of another. If there isn't
a law on the books against that, there ought to be.
