Why Study Growth? • Growth analyses provide – a more direct measure of learning – a more equitable basis for comparing schools that serve different student populations • Growth analyses allows us to locate schools with practices that are promising because students are learning, not just meeting the minimum standard © 2013 E 3 Alliance

Some Problems with Existing Measures 1. Change in percentage of student meeting the minimum TAKS/STAAR standard ignores: a) Annual changes in student population b) Academically where students entered school c) Large changes above or below the passing standard 2. Can’t compare changes in scale scores across students or grades © 2013 E 3 Alliance

Estimating Growth in Student Learning ü Student Growth Percentile (SGP) is the only student growth model we found that addresses the problems with existing methods Think of the pediatric growth charts for height and weight © 2013 E 3 Alliance

SGP Has Advantages & Disadvantages Advantages Disadvantages Method used in at least 15 states and is accepted by teacher unions Not used by TEA, but goal is to have wide use in Central Texas by 2013 -14 Opens up new dimension of discussion on what is an “excellent school” Requires data from all students in Texas, which E 3 Alliance has! Not affected by only helping “bubble” students Just looks at academic performance in core subjects Easily handles TAKS to STAAR change Requires data that becomes available a year after the test administration Very high year-to-year stability Methodology is open, nonproprietary, & relatively easy to understand concepts Schools get credit for students at ceiling

Calculating Student Growth Percentiles Step 1: Select the Students & Test Results Data • Select one grade level, one subject area, one test administration Ø Grade 6 Reading, 2011 © 2013 E 3 Alliance

Calculating Student Growth Percentiles Step 2: Identify Academic Peers • Select one grade level, one subject area, one test administration • Identify a subset of academic peers – students with identical scores in 2008, 2009, & 2010 Ø Grade 6 Reading, 2011 Grade 3, 2008: 2020 Grade 4, 2009: 2100 Grade 5, 2010: 2115 © 2013 E 3 Alliance

Calculating Student Growth Percentiles Step 3: Rank Order the 2011 TAKS Results • Rank order the academic peers by their 2011 test score © 2013 E 3 Alliance 1753 1790 1806 1976 1995 2018 2050 2085 2108 2210 2238 2250 2285 2297 2305 2386 2455

Calculating Student Growth Percentiles Step 4: Rank Order the 2011 TAKS Results • Rank order the academic peers by their 2011 test score • Assign each student a percentile rank © 2013 E 3 Alliance 1753 1790 1806 1976 1995 2018 2050 2085 2108 2210 2238 2250 2285 2297 2305 2386 2455 1 25 50 75 99

Calculating Student Growth Percentiles Step 4: Rank Order the 2011 TAKS Results • Rank order the academic peers by their 2011 test score • Assign each student a percentile rank • Repeat Steps 1 through 4 until all results are incorporated © 2013 E 3 Alliance 1753 1790 1806 1976 1995 2018 2050 2085 2108 2210 2238 2250 2285 2297 2305 2386 2455 1 25 50 75 99

Student Growth Percentiles To get the CAMPUS growth score • Select all students in a school • Rank order their student growth scores • Find the middle score, 50 th percentile 78 75 74 67 66 63 63 61 60 58 56 54 48 37 23 19 14 © 2013 E 3 Alliance
