Many of the findings in this report contradict trends that appear in publicly reported data. For instance, publicly reported statistics indicate that CPS has made tremendous progress in elementary math and reading tests, while this analysis demonstrates only incremental gains in math and almost no growth in reading. The discrepancies are due to myriad issues with publicly reported data—including changes in test content and scoring—that make year-over-year comparisons nearly impossible without complex statistical analyses, such as those undertaken for this report. This leads to another key message in this report: • The publicly reported statistics used to hold schools and districts accountable for making academic progress are not accurate measures of progress. For this study, we addressed the problems in the public statistics by carefully constructing measures and methods to make valid year-over-year comparisons. This allowed us to create an accurate account of the progress made by CPS since the early 1990s. The Consortium on Chicago School Research (CCSR) at the University of Chicago has a long history of tracking trends in Chicago’s schools. Through 20 years of studying the district, we have developed methods for using student data to create indicators that are comparable over time, adjusting for changes in tests, policies, and conditions that make the publicly reported statistics unsuitable for gauging trends in student performance.

Some bodies been lying...

“he discrepancies are due to myriad issues with publicly reported data—including changes in test content and scoring—that make year-over-year comparisons nearly impossible...”

Yes, that’s the idea.
