Summary of Learning Poverty Updates and Revisions (April 2024)

Core Content

This document outlines the updates and revisions to the Learning Poverty (LP) estimates for the April 2024 release, which includes data from 125 countries. The reference year for the release is 2019, aligning with the previous 2022 release. The updates are based on new learning assessments and revised enrollment data, and the methodology for selecting assessments and enrollment indicators remains consistent.

The LP indicator is calculated as a combination of Schooling Deprivation (SD) and Learning Deprivation (LD), with the formula:

$$
L P = S D + \left[ (1 - S D) * L D \right]
$$

Where:

• SD is the share of primary-aged children who are out-of-school.
• LD is the share of pupils below the minimum proficiency level in reading.

Main Points

1. Key Changes in the April 2024 Release

• New Countries Added: Kenya, Kosovo, and Uzbekistan are newly included in the Learning Poverty estimates.
• New Assessment Data: PIRLS 2021, AMPL-b (Kenya), and policy-linked NLAs (Pakistan) are now used to update LP estimates.
• Updated Enrollment Data: In 49 countries, enrollment data was revised or updated, with 47 also involving changes in assessment data.
• No Global or Regional Aggregates: Only country-level estimates are updated in this release.
• Data Sources: Learning assessments are sourced from international and regional organizations like IEA, UIS, and others, while enrollment data is sourced from UIS or country teams.

2. Methodology and Data Selection Hierarchy

The methodology for selecting assessments is based on a preference hierarchy:

1. Priority Rank 1: International/regional assessments in reading (e.g., PIRLS, LLECE, PASEC, SEA-PLM).
2. Priority Rank 2: International/regional assessments that allow statistical or policy linking (e.g., AMPL-b).
3. Priority Rank 3: National assessments that allow linking with international or regional assessments.
4. Priority Rank 4: International assessments in other subjects (e.g., TIMSS for science).
5. Priority Rank 5: Other national assessments for interim reporting.

The preferred enrollment indicator is the Adjusted Net Enrollment Rate (ANER), with some exceptions where country team data is more recent or relevant.

3. Learning Deprivation (LD) and Schooling Deprivation (SD) Updates

• Learning Deprivation: Updated based on PIRLS 2021 data for 52 countries.
• Schooling Deprivation: Updated in 49 countries, with some changes in enrollment definition or year.
