The state Education Department today released the results of this year's math and reading tests, showing that four school districts in Allegheny County failed to make adequate yearly progress under the federal No Child Left Behind Act.

The four districts are Pittsburgh, Duquesne, Sto-Rox and Woodland Hills. Sto-Rox is in the warning category, but the other three are in the most serious category, corrective action 2, Pittsburgh and Duquesne for the second year and Woodland Hills for the first year.

The AYP standard this year calls for at least 63 percent of students proficient or advanced in reading and at least 56 percent proficient or advanced in math. This is an increase over last year's requirement of 54 percent in reading and 45 percent in math.

However, there are other ways schools and districts can make AYP, including making significant progress even though the scores fall below the mark.

In addition to the districts, a number of schools within districts failed to make AYP, including some that missed on subgroups, such as special education students.

AYP is based on the results of the Pennsylvania System of School Assessment tests given in math and reading in grades 3 through 8 and grade 11 as well as attendance and graduation standards.
