Report Overview

This technical report details the methodology for the 2024 American Mathematics Educator Study (AMES) surveys, conducted via the RAND Corporation’s American Educator Panels (AEP) on behalf of the Bill & Melinda Gates Foundation. The study aims to understand mathematics learning opportunities from elementary through postsecondary education, with a focus on equitable access for Black, Hispanic, and lower-income students.

Key Objectives

To investigate barriers to high-quality mathematics education and identify factors influencing instruction and student access.
Surveys conducted in spring 2024 for teachers (ATP) and school leaders (ASLP).

Sample and Population

ATP: Targeted 3,100 public school mathematics teachers (surveyed in four oversampled states: California, Florida, New York, and Texas).
ASLP: Targeted 3,300 school leaders (principals), including oversamples in high school principals from Texas and Washington.
Both panels use nationally representative samples, with oversampling to increase state-specific representation.

Survey Administration

Delivery: Online, English-only, with an approximate completion time of 15 minutes.
Section Assignment: Based on grade bands (K-5, 6-8, 9-12) to reduce cognitive burden.
Additional Detailed Content: Section on college and career pathways for high school principals.

Weighting Process

Calibrated Weighting: Used to adjust for non-response and sample representativeness at the national and state levels.
Three-Step Process:
1. Calibration Weight: Adjusts for individual- and school-level characteristics to match population data.
2. Sample Selection Weight: Accounts for probability of being selected for the survey.
3. Response Weight: Accounts for participation likelihood.
Recalibration and Trimming: Ensures final weights align with population distributions.

Survey Completion and Reach

ASLP: 2,272 completed responses; total sample size after supplementary analysis was 3,631.
ATP: 3,114 completed responses from a survey pool of 6,682.
Completion Rates: ASLP achieved a 35.1% rate, while ATP had a 50.4% completion rate.

Non-response and Survey Quality

Adjustments made for response bias to ensure data representativeness.
Ensures analysis focuses on current-year trends rather than longitudinal tracking.
