  1. DCAS Issues Overview Jeff Klein Appoquinimink School District

  2. The move from DSTP to DCAS • More accurate measure of student ability due to its adaptive nature • Ability to measure growth longitudinally • Provide better information to inform instruction • Immediate Feedback • Flexibility in Administration • Identify Strengths and Weaknesses

  3. Is the DCAS more accurate than DSTP? • It has been extremely difficult getting any psychometric data on the DCAS • The following is what we do know: • The conditional standard of error of measurement appears to be no better than the DSTP.

  4. What is Standard Error of Measurement? • It represents the amount of variance in a score resulting from factors other than achievement. • If a single student were to take the same test repeatedly (with no new learning taking place between testings and no memory of question effects), the standard deviation of his/her repeated test scores is denoted as the standard error of measurement.
