The bookmark locations resulting from the standard-setting process were translated to scaled score cut points for each performance level using item response theory. The CSAP reading and writing scales range from 300 to 720. The cut points for each performance level for Reading and Writing are listed in the table below. Students with scaled scores below 445 demonstrated unsatisfactory performance in reading. Every item on the assessment was selected, revised, or developed to measure a benchmark of the Colorado State Model Standards.
Preliminary examination indicates a high degree of construct validity.
An independent panel of fourth grade teachers will be convened to evaluate the degree to which each item measures the standard and benchmark it was intended to measure.
