Setting a college-readiness cut score for the CRMT
CRMT Working GroupAugust 19, 20091:30-3:30
Pilot test summary
Current MPT-I placement cut scores
Group discussion
Purpose
2008-2009 CRMT Pilot Study
To relate MPT test scores to subsequent course grades to assist in setting CRMT college readiness cut score
Research Questions
How does student performance on the MPT-G compare to performance on the MPT-I?
How well do student test scores predict student grades?
Method
2008-2009 CRMT Pilot Study
Students at four-year universities took the MPT-G (n = 557) or the MPT-I (n = 692) for placement into courses
Students at other campuses were offered the opportunity to use test scores for placement at four-year universities
Tests administered between October 2008 and June 2009
Edmonds CC (n = 89)
Spokane Falls CC (n = 137)
TESC (n = 34)
21 high schools (n = 2220)
Results
2008-2009 CRMT Pilot Study
Test Reliability
Both the MPT-G and MPT-I showed excellent internal consistency ( = .84 and .85, respectively)
Test Difficulty
The MPT-G was more difficult than the MPT-I (Mns = 18.4 and 20.4, respectively; percentage equivalents = 52.6% and 58.3%)
2008-2009 CRMT Pilot Study
Test Difficulty (continued)
The difference in test difficulty was observed for all three educational sectors, but was most pronounced at four-year institutions
Average total score by test type and institution type
Results
2008-2009 CRMT Pilot Study
Test Difficulty (continued)
Students enrolled or enrolling in college level courses scored 6 points higher than students taking courses below college level
Average total score by test type and course level

Course Grades
MPT-G and MPT-I scores were significantly correlated with subsequent math course grades both at high schools and four-year schools (r .4)
Results
2008-2009 CRMT Pilot Study
Course Grades (continued)
Students who passed their math course (grade 2.0) tended to have scored significantly higher on the MPT than did students who did not pass
Results
Average total score by course level and grade (four-year schools)
2008-2009 CRMT Pilot Study
Course Grades (continued)
The probability of passing a course generally increased with total test score
Results
Observed rates of success in non-precalculus/calculus college level courses as a function of total test score (four-year schools)
2008-2009 CRMT Pilot Study
Course Grades (continued)
The probability of passing a course generally increased with total test score
Results
Observed rates of success in non-precalculus/calculus college level courses as a function of total test score (four-year schools)
Conclusions
2008-2009 CRMT Pilot Study
Both tests show good discriminant validity in the superior performance of students taking college level math courses over those in pre-college level courses
Both tests show good predictive validity by the significant correlations between total test scores and mathematics course grades
Both the MPT-G and MPT-I show excellent reliability
