English Learner Progress Indicator Calculation
Methodology for measuring performance on English Learner Progress Indicator.The ELPI is based on English learner (EL) performance on the English Language Proficiency Assessments for California (ELPAC) Summative Assessment (SA). For the 2019 Dashboard, the CDE will only have two years of ELPAC SA results from the spring 2018 and 2019 test administrations. As a result, the CDE will report ELPI Status only in the 2019 Dashboard.
ELPI Status measures progress toward English language proficiency (ELP). EL students taking the ELPAC SA in grades 1 through twelve in the current year with both a current and prior year ELPAC SA performance level are included in the ELPI Status calculation.
To determine EL progress toward ELP in ELPI Status, ELPAC SA student performance levels in both the current and prior year are converted to ELPI levels. Each student's current year ELPI level is compared to their prior year ELPI level. Those students increasing one or more ELPI levels or maintaining the ELP criterion (Level 4 on the ELPAC SA) are counted as making progress toward ELP. The student level results are aggregated to compute the ELPI Status Rate at the school-and LEA-level.
More information regarding the ELPI methodology will be available during the week of December 9, 2019 in the California School Dashboard Technical Guide (PDF).
Calculations
In the 2019 Dashboard, the ELPI Status rate reflects EL progress toward ELP.
ELPI Status Rate Calculation Formula
ELPAC SA Takers Who Increased at least 1 ELPI Level Between the Current and Prior Year
plus
ELPAC SA Takers Who Maintained the ELP criterion (Level 4) Between the Current and Prior Year
divided by
Total Number of ELPAC SA Takers with Both a Current and Prior Year ELPAC SA Level
The complete business rules will be available to view during the week of December 9, 2019 in the California School Dashboard Technical Guide (PDF).
Determining Status Levels from the Status Rate
The ELPI Status rate reflects the number of ELs who moved up at least one ELPI level or maintained the ELP criterion (Level 4 on the ELPAC SA) from the prior to the current year divided by the number of ELPAC SA takers with both a current and prior year ELPAC SA level. The proposed Status rate cut scores for each of the Status levels are:
| Status Level | Proposed Status Rate Cut Score |
|---|---|
| Very Low |
Less than 35% of EL students increased at least one ELPI level or maintained the ELP criterion (Level 4). |
| Low |
35% to less than 45% of EL students increased at least one ELPI level or maintained the ELP criterion (Level 4) |
| Medium |
45% to less than 55% of EL students increased at least one ELPI level or maintained the ELP criterion (Level 4). |
| High |
55% to less than 65% of EL students increased at least one ELPI level or maintained the ELP criterion (Level 4). |
| Very High |
65% or more of EL students increased at least one ELPI level or maintained the ELP criterion (Level 4). |
Example: Diamond Elementary had the following ELPI Status rate:
- 57 percent of EL students increased at least one ELPI level or maintained the ELP criterion (Level 4)
Using the table above, we see that Diamond Elementary would be given a Status level of ‘High’ based on its Status rate of 57 percent.
