CRMT Working GroupAugust 19, 2009130-330

• Pilot test summary
• Current MPT-I placement cut scores
• Group discussion

2
2008-2009 CRMT Pilot Study
Purpose

• 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?

2008-2009 CRMT Pilot Study
Method

• Tests administered between October 2008 and June
  2009

• 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

• Edmonds CC (n 89)
• Spokane Falls CC (n 137)

2008-2009 CRMT Pilot Study
Results
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)

Results
Test Difficulty (continued) The difference in
test difficulty was observed for all three
educational sectors, but was most pronounced at
four-year institutions

2008-2009 CRMT Pilot Study
Results
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

2008-2009 CRMT Pilot Study
Results
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)
8
2008-2009 CRMT Pilot Study
Results
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
Average total score by course level and grade
(four-year schools)

2008-2009 CRMT Pilot Study
Results
Course Grades (continued) The probability of
passing a course generally increased with total
test score

2008-2009 CRMT Pilot Study
Conclusions

• Both the MPT-G and MPT-I show excellent
  reliability

• 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
