1. English Assessment Validity February 2012 Michael Orkin, Jo Ann Phillips, Hui Zhang, Sheryl Queen Office of Institutional Research Peralta Community College District 1

2. English Assessment Test New Peralta students take assessment tests for placement in English classes. Course placement from test scores is recommended but not mandatory. A student can take courses without placement tests if prerequisites are met. 2

3. ACT Compass Test Peralta currently uses the ACT Compass test, CENG, for English placement. CENG tests English proficiency with separate writing and reading tests. This will soon change... 3

4. Statewide Online Assessment From Student Success Task Force, January, 2012: “… all students will have access to common online assessment tools for English, mathematics and ESL and to pre-testing programs that help improve assessment outcomes. They also will be able to take the results of their tests to any community college in the state.” 4

5. For now: ACT Compass Test Placement in English Courses A decision rule based on the two test scores selects an English course: transfer level (English 1A) degree applicable (English 201A) Pre-collegiate (Basic Skills). 5

6. Placement in English Course If the writing score is less than 22, the student is not assessed into a course and must see a counselor. 699 students in the sample data had low writing scores and were excluded. 6

7. Data Students taking CENG-recommended English courses in Fall 2008, Spring 2009, Fall 2009, Spring 2010. Took test immediately preceding semester when they took English course. Never took test prior to semester when they took English course. 7

8. Validity Validity measured in three ways: Relationship between assessment scores and grades. Comparison of assessed and non-assessed. Comparison of students who took the “right” course (recommended by CENG) and “wrong” course (not recommended by CENG). 8

16. Predicted Chance of Success As test scores get higher, does predicted chance of success increase? We use logistic regression. 16

21. Assessment vs. No Assessment Do assessed students do better in their assigned courses than students who don’t take the assessment test? We use ANOVA and Chi Square tests. 21

34. Conclusions English assessment test validity confirmed. Generally assessed results aren’t much different from non-assessed. Most students take English 1A. Students assessed into English 1A do significantly better than “wrong” English 1A students. Reading test most sensitive. 34
