The race for City Hall

Jobs and schools promise to be top issues in next year’s city elections. The mayor’s education agenda faces its toughest test in the African-American communities that gave him strong support in 2011.

State says student test scores set to plummet under higher standards

Next year, parents likely will get a rude awakening when they are handed their child’s ISAT scores. After a decade in which ISAT cut scores crept down, state officials are poised to raise them, thereby likely reducing the number of students who meet or exceed standards.

The Illinois State Board of Education is scheduled to vote on the proposed changes at their meeting on Thursday. The move comes in anticipation of a new, tougher standardized test expected to be ready for use in 2014. The new test will be based on the Common Core standards, which have been adopted by 45 states and the District of Columbia. The Common Core standards are thought to be more rigorous than current state standards.

If the change is approved, ISBE projects that the percentage of students statewide who meet or exceed standards on the ISAT will drop by 20 points in reading and math. ISBE officials will analyze the expected effects on individual districts in the coming weeks, ISBE spokesman Matt Vanover said.

If CPS has the same projected decrease, about 50 percent of students would meet standards on the ISAT—a similar percentage as in 2005, before the state lowered cut scores. In 2006, the cut scores were recalibrated and CPS saw a 15 percentage point jump in students meeting or exceeding standards. Last year, 76.4 percent of students in CPS met standards on the ISAT.

“Raising expectations is never easy, and the anticipated drop in students’ scores will be significant,” said State Superintendent Chris Koch in a press release. “However, we must seize this opportunity to tap into our children’s full potential and better prepare them at an earlier age to compete for jobs in a global economy.”

CPS is planning on sending letters to parents to explain to them what is going on, said CPS spokeswoman Becky Carroll.

Another reason for the recalibration, Koch said, is the state’s desire to align results on the high school standardized test, called the PSAE, with the ISAT. Only 51 percent of high school juniors met standards on the PSAE, compared to 82 percent on the ISAT.

Consequences for student retention, school probation, school ratings

Over the past two years, district officials have worked to prepare parents for the change. They have downplayed the results on the ISAT and, instead, tried to get parents to focus on the NWEA, a benchmark exam with results reported for the first time in 2011 on the district’s redesigned school progress reports.

The NWEA is considered to be more closely aligned with the Common Core standards. Currently, the NWEA is now the only test with results reported on a school’s progress report.

But, for CPS students, the change may have greater consequences. CPS is the only school district in the state that bases grade promotion partly on students’ ISAT scores. CPS officials have not said whether they plan to alter the policy in light of the cut-score increase or the Common Core assessment in coming years.

Also, ISAT results determine whether a school is placed on probation, as well as on the district’s rating scale.   

State standardized test scores also will be weighed into teacher and principal evaluations. However, growth will be considered, so low test scores, starting out, could be a benefit.

Some misinformation above

Percentiles will not be affected by the changes to the ISAT. Percentile a come from 30 questions on the first day of the test and are called SAT 10s. The rest of the test is used to determine the performance measure. ISBE told me that there will be a mismatch between the percentile and the performance cut. Children may have high percentiles and barely meet standards. CPS uses percentiles to determine promotion at the bench mark grades of 3,6 & 8th. The current policy is that the students need to be in the 24th percentile or above to be promoted. So the new cut scores will not affect promotion to the next grade.

CPS uses the average growth

CPS uses the average growth over 3 years on the ISAT (Composite, Reading, Math, Science, Exceeds and Attendance to place schools at levels. If the ISAT scores decrease how will they make those decisions and how will this affect schools? Is CPS having considering the Performance Policy and how it will be impacted by the change?
