The Comprehensive Testing Program (CTP 5) is a battery of assessments designed to provide instructionally useful information about student performance in the key areas of school achievement: listening, reading, vocabulary, writing, and mathematics. In addition, CTP 5 includes for test levels 3 - 10 two tests to measure verbal and quantitative reasoning. The results of these measures can be used to compare more content-specific, curriculum-based measures of performance (scores on the achievement tests) to the more general, derived skills that both result from and enable school achievement (scores on the reasoning tests). This comparison can prove to be highly useful, especially for identifying those students whose skills and achievement scores show marked discrepancies. The online version is available through the CTP Portal for instant scoring and a science test in test levels 3 through 10. We know time is of the essence, so all of our online assessments provide instant feedback to schools and students, enabling real time guidance for instruction and learning.
