  1. ACCUPLACERRWins Approval Again in California Ron Gordon Gordon Associates ACCUPLACERR Conference Las Vegas, 2005

  2. How it Started • MALDEF • Mexican American Legal Defense Fund • “Restricting Enrollment in courses with tests that have not been validated.” • Tests Must be Approved by the Chancellor • Enrollment cannot be restricted on the basis of test scores alone.

  3. The Legal Situation • Tests must be valid on the basis of content and either criterion or consequence. • Tests must demonstrate reasonable reliability • Tests must be free from disproportionate impact • Colleges must evaluate for content and consequence, and for disproportionate impact. • Colleges must set appropriate cut scores. • Colleges must develop a “multiple measures” approach to placement.

  4. ACCUPLACERR History • First Approved in 1993 for 6 Years • 1-Year Extension for all Tests • Submitted Data in Fall, 1998 • Approval Rejected in June, 1999 • Re-approved in January, 2000 for 6 years • Re-approved in January, 2005 until January, 2012

  5. Approval Process • Submit validity analysis from at least 6 California Colleges • Report must show that 75% of faculty and students agree that placement is accurate (consequential model) or that course grades correlate with test scores with Pearson’s R of .35 (criterion model)

  6. Approval Process • Demonstrate reliability • (test/retest model) • Item bias analysis • (DIF, linguistic bias, and Disproportionate Impact) • Specify user support • Manuals, technical help • ADA

  7. Gathering Data • 23 colleges participated • Surveyed faculty and students • Students could be under-prepared, adequately prepared, or over-prepared • More than 16,000 students surveyed • More than 900 faculty participated • Most colleges sent back individual completed surveys • A few input the data to electronic files

  8. Data Preparation • Identify students who had taken a prerequisite course • Group data by discipline and level • Code courses by level • First transferable course = 0 • Code survey results • Move Over-Prepared to next level • Cluster scores in increments of 5

  9. PlacementAccuracy

  10. Analysis • Frequency distribution of responses across score clusters • Objective: Determine whether ACCUPLACERR can place students with accuracy above 75% • Appropriate cut score is the point at which “Adequately Prepared” is near apex and “Over-Prepared” has not begun to increase significantly

  11. Typical Data Set

  12. Findings • ACCUPLACERR Tests Place Students with greater than 82% Accuracy • ACCUPLACERR Passes Tests for Disproportionate Impact • The New Arithmetic and Algebra Items Show No Linguistic Bias • The New Arithmetic and Algebra Items Demonstrate Exceptional Test/Retest Reliability

  13. Approval • Reading Comprehension, Sentence Skills, Arithmetic, Algebra, CLM, 3 LOEP tests Received Full Approval Until 2012

  14. Additional Findings • WritePlacer Plus and WritePlacer ESL showed no Linguistic Bias in Prompts or Instructions. • LOEP Listening Showed Significant Linguistic Bias • Negative ethnic references • Ethnically identifiable names in stereotypical circumstances

  15. Conclusions • ACCUPLACERR Remains an Effective Test for use in California Community Colleges. • WritePlacer Plus and WritePlacer ESL Have Moved a Step Closer to Approval in California • LOEP Listening Needs Work, but Appears to be an Effective Instrument for ESL Placement
