Predicting Proficiency… How MAP predicts State Test Performance
Paul Stern, District Enterprise Analyst, Vancouver Public Schools, Sarah Johnson, Accountability Project manager, Highline Public Schools, Burien, WA
Fusion 2012, the NWEA summer conference in Portland, Oregon

NWEA routinely produces “Linking Studies” that explore the alignment between the RIT Scale and state student proficiency exams. This presentation will share the results of an alignment study that applied a methodology developed by the Highline School District. The presentation will focus on how the results of the two methods differ and how Vancouver Public Schools will use this information to inform instruction and guide student interventions.

Learning outcome:
- Learn how to define proficiency using MAP cut scores.
- Understand the alignment of MAP to Washington’s State Assessments.
- Learn how alignment studies can be conducted and used to inform instruction

Audience:
- Experienced data user
- Advanced data user
- District leadership
- Curriculum and Instruction

Vancouver Public Schools serves approximately 22,000 students in Vancouver, WA, an urban/suburban district across the river from Portland. The presenter is the enterprise analyst within the Information Technology Services department focused on predictive analytics and performance measurement.

  2. 2. Overview• Background/The Value of Alignment Studies• Highline’s Regression Study• NWEA’s Linking Study• Multi-District Regression Study• Conclusions• Applying the Results
  3. 3. Learning Objectives• Learn how to define proficiency using MAP cut scores.• Understand the alignment of MAP to Washington’s State Assessments.• Learn how alignment studies can be conducted and used to inform instruction.
  4. 4. Value of Alignment StudiesResearchers align scales for one of two purposes:• Use results from measure “X” to predict the value of a harder-to-observe measure or outcome “Y”.• Use results from measure “X” to predict the value of a future measure or outcome “Y”.In our case, faculty and administration are interested inidentifying students who are likely to struggle on futurestate performance measures. By intervening early, wecan target resources to students who may not meet“proficiency”.

  6. 6. About Vancouver Public Schools• About 22,000 enrolled students• 6 High Schools (4 comprehensive, 1 magnet, 1 alternative)• 18% of students speak a language other than English at home• 49% eligible for free or reduced price lunch• The district serves half of the city of Vancouver, WA (across the river from Portland)
  7. 7. About Highline Public Schools• About 18,000 enrolled students• 15 High Schools (2 comprehensive, 6 small learning community, 1 magnet, 5 alternative, 1 skills center)• 43% of students speak a language other than English at home - 21% are ELL.• 67% eligible for free or reduced price lunch• The district serves neighborhoods of White Center, Burien, Des Moines, SeaTac and Normandy Park just south of Seattle.
  8. 8. Washington’s State Assessments• Measures of Student Progress (MSP) is given in grades 3-8 in math and reading.• High School Proficiency Exam (HSPE) is given in grade 10 in math. There is not a 9th grade test.• End of Course Exam (EOC1 and EOC2) given at the end of Algebra and Geometry courses regardless of the student’s grade. (Some middle school students take both the math MSP and an EOC).• The Writing and Science MSP and HSPE were not included in any of the following analyses.• A score of 400 is proficient in Reading & Math/EOC.
  9. 9. Highline’s Regression Study• In 2007, School and District Administration had been requesting ways to interpret student MAP scores in context of (then) WASL testing. One concern in particular was that students had been above average on the national norms, but yet were not meeting standard on the state assessment.• School staff also requested a way to quickly identify if a student was on track or not.
  10. 10. Highline’s Regression Study• Decided to do a regression analysis to predict WASL performance.• Ran correlations on multiple variables, and found that “HiMap” (max of last 3 test administrations) had a higher correlation with WASL than a single MAP score. • Weeds out test “bombs” and missing data
  11. 11. “HIMAP” Variable Defined Fall Winter SPRING HIMAP HIMAP HIMAP 5th Grade 5th Grade 5th Grade
  12. 12. Highline’s Regression Study• Rather than make a straight out prediction of whether a student will meet/not meet standard, we wanted to emphasize the possible prediction error.• Decided to find a cut on the MAP assessment to predict 400 on WASL, and then generate an error band around that where students would be considered “too close to call”• Used 4 points as a generous estimate of the standard error of the assessment (usually between 3-3.5)
  13. 13. Intervention Categories: 3 “Bands”• “Above Benchmark” students were those who performed more than 4 RIT points above the cut score. These students are considered on track to meet standard.• “Strategic” students were those who performed within 4 RIT points of the cut. These students are “too close to call” and should receive strategic intervention to meet standard.• “Intensive” students were those who performed more than 4 RIT points below the cut score. These students are unlikely to meet standard without intensive intervention.
  14. 14. Cuts for Fall, Winter and Spring• When the study was first done in 2008, regression analyses were performed using Spring MAP scores and WASL.• Growth norms were utilized to back track to get cuts for Fall and Winter• Cut scores and ranges were disseminated to teachers and administrators, along with an explanation of the scores.• Excel files for schools began including MAP scores, along with each students’ “BSI Indicator”, color coded in Red, Yellow and Green.
  15. 15. Predictive Validity• When a student’s indicator is compared to their actual performance: • Approximately 90% of students identified as “Above Benchmark” actually met standard. • Approximately 50% of students identified as “Strategic” actually met standard. • Approximately 10% of students identified as “Intensive” actually met standard.• These were generally true within about 10 percentage points
  16. 16. 2010 MSP• The analysis was re-run in 2010 following the first year of transition from WASL to MSP.• During the second analysis, regressions were run on each test window individually in each grade level, finding individual cuts, rather than using growth norms.• District budget cuts made high school MAP testing optional, and therefore High School was excluded.
  17. 17. NWEA’s Linking Study • Most recently updated in Feb, 2011 • Based on a sample of 271 schools in the Spring of 2010 • NWEA uses an Equi-percentile method to equate test results
  18. 18. Equipercentile Method ofAlignment • NWEA used a sample of students from 271 schools taking the 2010 spring assessment in WA. • For each grade and subject, identify the percentage of students in the study sample that met standard. • For each grade and subject, identify the RIT associated with the equivalent percentile from within the study sample.“If 40% of the study population in grade 3 mathperformed below the proficient level on the state test,we would find the RIT score that would be equivalentto the 40th percentile for the study population”
  19. 19. Multi-District Regression Study• Included 7 districts including Seattle, Bellingham, Vancouver, Highline, Sumner, Auburn, and Clover Park• Data covered the 2009-10 and 2010-11 academic years• The “cut score” for proficiency was consistent across both years at each grade level, so data from both years was pooled• Overall N of approximately 80,000
  20. 20. Independent Variables Created• Math Spring RIT (Winter and Fall as well)• Math Spring HIMAP (Winter and Fall as well)• Combined Spring HIMAP (sum of Read & Math) (Winter and Fall as well)• Math Winter HIMAP + Math MSP• Math Fall HIMAP + Math MSP(Comparable variables were also created for Reading)
  21. 21. Quality of CorrelationBest: (Corr: 0.78) • Spring RIT (but no predictive value, so Spring indicators will be ignored)Next Best: (Corr: 0.73-0.75) • Winter RIT • Winter HIMAP + MSP scale score (275-500) • Winter HIMAPThird Best: (Corr: 0.70) • Read Winter HIMAP + Math Winter HIMAP
  22. 22. Rationale for Selecting Winter HIMAP• Spring MAP test window overlaps MSP/HSPE test window.• Prior Year MSP scores not available for grades 3 and 10.• New students in district are missing MSP scores.• Not all students perform to their best ability on every test.• Many students do not take the Winter MAP.
  23. 23. Rationale for Selecting Winter HIMAPWinter HIMAP …• Is not very different in the quality of the correlation as compared to other options,• Maximizes the number of students for whom it can be applied, and• Is relatively easy to explain

  27. 27. Pro and Con of Do-It-YourselfPro: • Data are based on “our kids” (this is an emotional argument, not a statistical one). • Winter and prior spring estimates can be computed rather than estimated.Con:• It is a lot of work.• Controlling for test windows is complex.• NWEA results are very similar to DIY results.• Teachers who encounter the NWEA linking study will be confused about why our cut points are different.• … and did I say it was a lot of work?
  28. 28. Vancouver’s Plan to Move Forward• Use NWEA-published linking study to identify cut-point targets in each grade/ testing window.• Identify students as likely to meet standard, at risk, and not likely to meet standard based on their HIMAP RIT for that period and a 4 point band around the NWEA targets.• Estimate winter values based on the mid point between fall and spring. Estimate prior spring equal to subsequent fall value (no summer drop- off).
  29. 29. Applying the Results: Vancouver• Teacher tables with color coding to identify which students are likely to meet or not meet standard on the MSP/HSPE• Predictions of the number of students the district might expect to meet standard if no changes are made to the pace of student learning during the year.• Maintain a higher priority in the use of MAP to identify individual student learning needs and target instruction (using DesCartes)
