Description

Two publicly released synthetic benchmark datasets created by Schroeder et al. for evaluating LLM performance on NGSS-aligned middle- and high-school science items.

Components

• NGSS-aligned middle school and high school science benchmarks with a four-tier synthetic data quality gate pipeline: Two publicly released ground-truth benchmarks for evaluating LLM understanding of secondary science: "Our final dataset consisted of 1,078 items for middle school benchmark, and 1,150 items for the high school benchmark." Items were synthetically generated by Sonnet 4.6 Thinking, distributed across recall, conceptual understanding, and applied reasoning types and across 12 NGSS areas per level. Construction used "a four-tier data quality gate system" removing duplicates, enforcing Flesch-Kincaid reading-level ranges, and requiring a three-judge LLM panel to agree on both answers and standard alignment. Data and code are available on GitHub. (Schroeder et al. (2026))
