Description¶
The article proposes using the education polygenic score (education-PGS), a composite of genetic variants associated with completing more years of school, as a "molecular tracer" of students through the high school math pipeline. Because genetic sequence is fixed at conception and cannot be changed by educational experiences, comparing students equivalent in education-PGS but attending different schools can illuminate how achievement depends on contextual factors, complementing research on school-based factors such as instructional practices. The authors visualize genetically stratified flows using a river plot of course sequences by year.
Accounts¶
- Polygenic scores as a molecular tracer for studying flows of students through the STEM pipeline: The article proposes using the education polygenic score (education-PGS), a composite of genetic variants associated with completing more years of school, as a "molecular tracer" of students through the high school math pipeline.

Claims¶
- Higher education polygenic scores predict placement into more advanced 9th-grade math courses, robust to family SES, school SES, and school fixed effects [+M]
- Higher education polygenic scores predict persistence in mathematics coursetaking across four years of secondary school, robust to SES covariates, prior tracking, and school fixed effects [+M]
- School socioeconomic advantage buffers low-polygenic-score students from dropping out of math: the PGS-by-school-SES interaction on persistence is significant and negative [+M]
