HINSDALE — Hinsdale South High School failed to make adequate yearly progress for the sixth year in a row, as determined by the No Child Left Behind law.
But the levels required by the legislation are getting so high, Hinsdale Central did not reach the official target either. But Central was deemed to make adequate yearly progress based on lower thresholds the federal law allows.
Hinsdale High School District 86 as a whole failed to make adequate yearly progress.
No Child Left Behind each year raises the required percentage of students meeting or exceeding standards. The results are based on the math and reading scores from the Prairie State Achievement Exams juniors took last school year.
For 2013, 92.5 percent of juniors were required to meet or exceed standards. No group of students districtwide or at Central met that threshold.
Hinsdale South Principal Brian Waterman said 92.5 percent is virtually impossible to meet.
In addition to district totals, student achievement is broken down into categories of students, including race, low income and students with disabilities.
There must be at least 45 students in a category for their results to be reported separately. Each category is expected to meet the same target as the district as a whole.
However, the federal law sets lower thresholds, called safe harbor targets, for schools and subgroups that may not achieve 92.5 percent, but still make sufficient progress from the previous year.
But districtwide, no subgroup except white students, met the lower safe harbor threshold either.
The percentages ranged from 88.5 of Asian juniors meeting or exceeding the reading standards to 26.2 percent of black juniors meeting or exceeding the math standards.
At Hinsdale South, only 24 percent of black juniors met math standards and 36 percent of black students met the reading standards.
Among low-income students at South, 39.7 percent met the math standards and 51.5 percent met the reading standards.
Waterman said administrators do not wait for the report to take action. They are using interventions and analyzing the data further to determine which classes the students who did not meet standards to identify areas that need improvement.
