Polygenic scores (PGS) for educational traits and outcomes (e.g., math ability, reading ability, and educational attainment) are currently available to the public via direct-to-consumer genetic testing companies, such as GenePlaza. A PGS is a DNA-based genetic predictor in the sense that it places an individual’s sample of DNA on a spectrum from low to high. So, in theory, people with a high percentile rank PGS score for educational attainment would be likely to accrue more years of schooling in their lifetime than people with lower ranked scores.
