SGP Data Location You will find the student growth data in WAMS under your district’s Profile > Assessment Operations > File Downloads, under the 2017 Administration.

State Summary Data Using the cohort method to calculate SGPs results in state-wide medians of 50 for each grade and subject combination for the 2016-2017 school year.

Individual Student SGP File A flat file has been provided for all student records that are in your district’s SBA/EOC/AIM score file, including those with and without an SGP. Descriptions of the fields in this file are documented in Appendix A. The student-level file is a long file that includes one record or row for each SSID, test record and subject combination. Therefore, one student will likely have multiple records in the file.

Student Growth Plots The individual student growth plots show each student’s score history and SGPs in Math and Reading for grades 3-8.

 There is one pdf per school that is a catalogue of all student plots.  The catalogue includes all students that received SGPs as well as grades 3-8 students that did not receive an SGP, but still received a score.

For a more detailed description of the student growth reports, please see the following guidance document on the OSPI website: “Understanding a Student Growth Percentile Report”.

9/5/2017 Appendix C. Business Rules for Calculating Washington’s Student Growth Percentiles for the 2016-2017 School Year

Rules for Inclusion in SGP Calculations  Home-based and Private School Students: Home-based and private school students that receive public school services part-time are not included in the analysis, even if they took a state assessment.  F1 Visa: F1 Visa students are excluded.  Test Attempts: Only students with test attempt of ‘Tested’ are included. Therefore students that have a test attempt of previously passed or any other test attempt are not included.  Test Types: Student scores from DAPE, Portfolio, and AIM assessments were excluded. Students that were scored as Basic were included.  Assessment or Grade Repeat: If a student repeated a grade and received a valid score, they will not receive a growth percentile in the year they repeated the grade.  Administration: Spring assessment scores are included; tests from all other administrations are excluded.  Continuously Enrolled: Both continuously enrolled and non-continuously enrolled students were included in the calculations. However, continuously enrolled is a subgroup used for summary purposes in some of the reports and files.  SSID: Only students with a student state ID in the assessment file are included.  Scale Score: Only students who receive a scale score are included.  Valid Case: If the student did not meet any of the criteria above, they are identified as an invalid case. If a student met all of the criteria above, but did not have a prior year score, they would still have a value of ‘VALID_CASE’ in the ValidCase field.

Rules for Calculating SGPs  Students are compared to other students in the same grade in the same subject. They are compared to their ‘academic peers’, those that scored statistically similar to them. Students are only compared to others based on their score history, not on any other characteristics, such as demographics or program participation. The percentiles are calculated using a method called quantile regression. For more information on how the student growth percentiles are calculated, please see Washington’s Growth Model Report written by Damian Betebenner, the developer of the student growth percentile model.  Students must have tested in the current and at least the previous year to generate an SGP. In addition to the previous year’s score, any consecutive previous scores will also be used. The student-level data provided to districts includes a data field (“SGPNormGroup”) which lists the year and grade of all the scores used to calculate that students SGP.

9/5/2017  Percentiles are calculated and provided for English Language Arts and Math, not including the Year 1 and Year 2 end of course assessments. If students tested in the grades listed below, in addition to receiving valid scores in the year prior, they will receive a student growth percentile.

Grade Tested Math English Language Arts 4th Grade SBA SBA 5th Grade SBA SBA 6th Grade MSP/SBA MSP/SBA 7th Grade MSP/SBA MSP/SBA 8th Grade MSP/SBA MSP/SBA
