La. Admin. Code tit. 28 § XI-503

Current through Register Vol. 50, No. 11, November 20, 2024

Section XI-503 - Calculating a High School Progress Index

A. Beginning in the 2017-2018 school year (2018 SPS), the progress index will be calculated for algebra I, geometry, English I, and English II assessments as follows.

B. Progress is measured between a student's 8th grade ELA and math assessments and the LEAP 2025 ELA and math assessments (algebra I, geometry, English I, and English II).

1. If a student took only the high school LEAP 2025 assessment in middle school, the middle school progress index results will carry forward to the high school.

2. Retests will not be counted in the progress index.

C. For students scoring unsatisfactory, approaching basic, or basic on the baseline assessment, the progress index will award 150 points for each English and math score meeting or exceeding the growth to mastery target.

1. The growth to mastery target for students taking their first high school LEAP 2025 in a content area will be calculated by adding to the baseline scaled score the difference between the scaled score required for mastery (750) and the baseline scaled score divided by two. The growth to mastery target for students taking their second high school LEAP 2025 in a content area will be mastery (750).

2. Growth to mastery targets will be rounded to the nearest whole number but must be at least one point above the baseline scaled score.

D. For students scoring mastery on the baseline assessment, the progress index will award 150 points for meeting or exceeding the "continued growth" target.

1. The continued growth target will be calculated by adding to the baseline scaled score the difference between the English II and geometry scores required for advanced and the prior year assessment scaled score divided by two. For students taking their second high school LEAP 2025 in a content area, the continued growth target is a score of advanced.

2. Continued growth targets will be rounded to the nearest whole number but must be at least one point about the baseline scaled score.

3. If the continued growth target as calculated above exceeds the minimum score for advanced in the current assessment, the target is advanced.

E. A score of advanced in the current year will be awarded 150 points in the progress index.

F. If a student does not earn 150 points in B-D above, the value-added model will be used to measure individual student performance relative to similar peers.

1. For the purpose of school performance score calculations, the value-added model uses student characteristics including but not limited to prior academic achievement up to three years, special education exceptionality, economically disadvantaged status, English learner status, gifted status, section 504 status, suspensions, mobility, and absences to estimate typical outcomes for comparable students in ELA and math based on a longitudinal dataset from all students who took Louisiana state assessments in grades 3-12. Based on typical outcomes for comparable students, each student is assigned an expected score.

2. The difference between each students actual achievement and that students expected score is the growth result. If actual achievement for a student was higher than expected achievement for that student with that history (e.g., actual: 725; expected: 700), then the result would be positive (e.g., growth result: 25). In contrast, if the actual score was less than the expected score, the growth result would be negative.

3. Each student growth result will be compared to all other student residuals in the same subject area (ELA or math) and percentile ranked from the 1st to 99th percentile.

4. Value-added model points will be awarded as follows.

Student Growth Percentile	Index points
80-99th percentile	150
60-79th percentile	115
40-59th percentile	85
20-39th percentile	25
1-19th percentile	0

5. Students scoring mastery in the current year shall be awarded up to 150 points, but no fewer than 85 points in the progress index, including students who score in the 1st to 39th percentiles of VAM.

G. The progress index calculation will include all students who meet the inclusion requirements outlined in Chapter 5 and have eligible LEAP or EOC assessment results in both the current and prior school year for the same content area. Student scores will be excluded from the progress index (growth to mastery and value-added model) if any of the following are true:

1. student did not take the ELA or math assessment or assessment result was voided in current or prior year;

2. student has more than one missing prior year score in the available subject tests. The value-added model uses tests in all contents available to analyze any given content. For example, if the contents available in the prior year were ELA, math, science, and social studies, a student missing more than one score in those contents would be excluded;

3. assessment results for current or prior school year are in multiple grade levels in the same year;

4. current or prior year assessment results could not be matched to a valid student enrollment record needed for student characteristics used in the model;

5. insufficient numbers of comparable students for valid calculations within the value-added model;

6. student is dually enrolled in algebra I and geometry courses (applies to geometry only).

H. The progress index will combine the results of two school years.

1. If only one year of data is available for a school, the progress index will be calculated based on one year only.

2. All students who meet the inclusion rules at a school for each individual school year will be included in the combined calculation. For example, in 2018-2019, the number of points earned by students in 2018-2019 will be added to the number of points earned by students in 2017-2018 and divided by the total number of students in 2018-2019 and 2017-2018.

3. In 2017-2018 only, the high school progress index will be based only on one year of results.

I. For the 2020-2021 school year (2021 SPS) only, the "growth to mastery" and "continued growth" targets will be calculated using the scale scores from the 2018-2019 LEAP 2025 administration as the "prior year scale score."

J. When considering prior academic achievement up to three years in the value-added models, as defined in E.1 of this section, the three most recently available years may be considered in instances where assessments were not administered statewide for a given school year.

K. For the 2020-2021 school year (2021 SPS) only, the progress index will combine results from the 2018-2019 and 2020-2021 school years.
