The Partnership for Assessment of Readiness for College and Careers, or PARCC, is administered to third- through eighth-graders in Illinois, testing them in reading and math based on Common Core standards. A composite score combines the results of the subject tests.
According to Tonti Elementary School composite scores for 2017, 27.7 percent of low income students passed the tests. Meanwhile, 62.5 percent of non low income students passed.
Students who passed either met or exceeded expectations and are considered prepared for the next grade level, college or work. Students who failed either partially met, approached or did not meet expectations.
