Maybe "study" is the wrong term. How about an "analysis" of data
using regression techniques? I attended the school board meeting
where the Strib's education beat writer got that "fuzzy quote," and I
taped the meeting later that evening. Audrey Johnson was there.
Dennis Schapiro was not there. I would like to get a clarification from
Mr. Heistad himself about that "study" which Dennis Schapiro says
David Heistad says doesn't exist.
And I would like to know something about those long-term studies
to which Dennis Schapiro refers, like the title, who did the research
and where they got the money for their research. Or are we dealing
with a set of nonexistent studies?

In the extract from "What Matters Most" cited above [see footnote],
Linda Darling-Hammond says, "In an analysis of 900 Texas school
districts, Ronald Ferguson found that teachers’ expertise—as
measured by scores on a licensing examination, master’s degrees,
and experience—accounted for about 40% of the measured variance
in students’ reading and mathematics achievement at grades 1 through 11,
more than any other single factor. He also found that every additional dollar
spent on more highly qualified teachers netted greater increases in student
achievement than did less instructionally focused uses of school resources
(see figure 4 in full report).
"The effects were so strong, and the variations in teacher expertise so great
that, after controlling for socioeconomic status, the large disparities in
achievement between black and white students were almost entirely
accounted for by differences in the qualifications of their teachers.
An additional contribution to student achievement was made by lower
pupil-teacher ratios in the elementary grades. In combination, differences
in teacher expertise and class sizes accounted for as much of the
measured variance in achievement as did student and family background
