How Can Teacher Evaluation Be Connected to Student Achievement?

State Achievement Measures Option 1 Student Achievement Status Models

Post-test only Not a growth measure Can be: –Norm-referenced achievement tests –Criterion-referenced, end-of-course/year tests Examples: ITBS, SAT, GRE, State EOC tests

Status Models: Questions Answered How well did Miguel perform compared to a national norm group of 5th grade students? (norm referenced) Did Miguel reach a pre-set benchmark score for proficiency or mastery on the 5th grade math test? (criterion referenced)

Problem with Status Models End of Year Beginning of Year

Status Models Provide Valuable Information... but not for teacher evaluation.

State Achievement Measures Option 2 Student Growth Percentile Model Note: SPG slides developed by Dr. Deborah Jonas, VA DOE

Student Growth Percentile Model Questions Answered How much did Miguel improve from 4th grade to 5th grade relative to his academic peers (students with the same score in 4th grade or similar achievement histories)?

Student Growth Percentile Characteristics Percentiles express the percentage of cases that fall below a certain score. –SGPs are reported between 1 and 99. –Higher numbers represent higher growth and lower numbers represent lower growth. Uncorrelated with prior achievement –Low achieving students can show high growth –High achieving students can show low growth

Same Three Students - in Grade 7 Example only. Note that SGPs account for as much historical data as are available.

Goal Setting Process

EXAMPLE USING TEST DATA Goal Statement For the 2009/10 school year, all of my students will demonstrate measurable growth in mathematics. At least 80% of my students will meet or exceed the benchmark of 50th percentile or above on the percentile rank distribution for STAR.
