Ranked by the National Center on Response to Intervention (NCRTI)
Classworks Universal Screeners measure readiness for instruction, diagnose strand-level areas of weakness, identify baseline learning levels, and measure growth. This formal assessment is then used to initiate the Response to Intervention (RtI) process to identify students requiring additional instructional support in Tiers II or III.
Test reliability refers to the test score consistency and accuracy. Reliability values range from 0 to 1.00, with higher values indicating higher reliability. Using the data collected from the multi-state field test, the average reliability for the Universal Screeners from grades K through high school was found to be:
- Mathematics - .88
- Reading - .90
These high internal consistency measures indicate that the Universal Screeners are able to provide a reliable measure of student performance in reading and mathematics.
In addition to the reliability and validity of the measures, the Universal Screeners were also evaluated with regard to the accuracy of classifying students as at-risk in comparison to an independent measure. Classworks Universal Screeners also ranked high in accuracy to identify at-risk students:
- Mathematics - 93%
- Reading - 97%
It is important that the screeners are able to appropriately identify students who are at-risk and those who are not at-risk. In particular, it is critical that students at-risk are properly identified as being at-risk so that the students can get the instructional help that they need.
