Uses for DAR

The Diagnostic Assessments of Reading (DAR) assess students’ relative strengths and weaknesses in key areas of student learning in reading. The DAR can be used with students of all ages and abilities in diverse educational settings. The DAR can be administered for Title I, Reading First, Special Education, adult literacy, or other reading program placement. The DAR assess all five components required for an effective Reading First program: phonemic awareness, phonics, vocabulary development, reading fluency, and reading comprehension.

The DAR were designed for use by classroom teachers, reading specialists, special education teachers, psychologists, and other professionals charged with helping students read better. No special qualifications or certifications are required to administer the tests. The DAR are available in two forms (A and B), which allow for pre- and posttesting. Teachers can use the DAR to develop a constructive student-teacher relationship, assess the reading development/growth of a given student, and prescribe individualized instruction to meet a student’s needs.

The DAR program is based on extensive research and experience, and it meets the highest technical requirements for

  •   demographic characteristics of the standardization population;
  •   reliability, including inter-rater reliability;
  •   content validity, including DIF and comparison of DAR content to essential components of 
      reading outlined by the National Reading Panel;
  •   criterion-related validity; and
  •   construct-related validity.


DAR scoring is simultaneous with administration. DAR ScoringPro creates datasets of students’ results, aggregates and disaggregates students’ scores, and allows test administrators to print an Individual Report/Profile and a Class List Report. ScoringPro provides meaningful, easy-to-interpret scores for each subtest.
