significantly improve educational achievement. However, the national data fails
to support this premise. Reviewing 152 studies of teacher/pupil ratios, Hanushek
found only 27 were statistically significant. Fourteen studies found a positive
correlation and 13 studies found a negative correlation between smaller

smaller class sizes than Detroit Public Schools. Class sizes among private
schools tended to
range between 14 and 2.5 pupils. The average class size in the Detroit Public

per enrolled student, has 15 students per teacher, yet its dropout rate at 47%
was nearly identical to that of the Detroit Public School District.
