Core Documents
IMPACTER-owned and open-access documents behind the Brief. Paywalled sources are linked to their existing hosting, never duplicated here.
Implementation Workplan Crosswalk
The master crosswalk mapping every BHPM contract deliverable and activity to its owner, timeline, and Commission reporting domain across the nine-deliverable Implementation Workplan (internal — link pending).
Hand this to anyone asking which partner owns a given deliverable, activity, or due date across the two-year BHPM contract.
Technical Note v6.x — Stratified Human-in-the-Loop Calibration
IMPACTER's internal technical note on the stratified, weekly human-in-the-loop sampling layer that calibrates the scoring pipeline: sampling design across attribute, score band, prompt, and item type, plus drift monitoring and retraining governance.
Hand this to anyone asking how IMPACTER keeps its scoring models calibrated and audited over time — this document describes the sampling and governance methodology, not the model architecture (see the Model Card for architecture and accuracy figures).
Behavioral Health Screening Guide (BHPM)
A guide to performance-based behavioral health screening through authentic student voice, developed for the BHPM project and its participating LEAs.
Hand this to an LEA team asking how IMPACTER's screening approach differs from a traditional self-report instrument.
Human-Friendly Guide to IMPACTER's ML Model
A plain-language walkthrough of how IMPACTER's machine learning model reads a student's open-ended response and produces a score, written for non-technical readers.
Hand this to a superintendent, board member, or parent asking how the scoring actually works, without the technical jargon.
IMPACTER Model Card v6.0
The canonical, published model card for IMPACTER's Model Suite v6.0: a fine-tuned DeBERTa-v3-base encoder with a CORAL ordinal regression head (184M parameters), averaging 0.918 QWK, 77.3% exact-match accuracy, and 98.0% adjacent (+/-1) accuracy against human raters across the eight durable-skill attributes, with promotion gates of QWK >= 0.70, degradation <= 0.10, and |SMD| < 0.10.
Hand this to anyone asking for IMPACTER's official, versioned accuracy figures and promotion criteria — the single approved source for any model-performance number cited on this site.
Arnold, Liu & Abe (2007) — Temporal Causal Modeling with Graphical Granger Methods
Arnold, A., Liu, Y., & Abe, N. (2007). Temporal causal modeling with graphical Granger methods. Proceedings of the 13th ACM SIGKDD International Conference on Knowledge Discovery and Data Mining, 66–75. https://doi.org/10.1145/1281192.1281203 — introduces Lasso-Granger for learning temporal dependency among multiple time series via variable selection.
Hand this to anyone asking about the academic lineage behind IMPACTER's planned Year 2 upstream-lever and dosage analysis with Stanford Medicine; first author Dr. Andrew Arnold is IMPACTER's Senior Scientific Advisor and the architect of its scoring pipeline.
Ober et al. (2026) — Using LLMs to Identify Indicators of Persistence
Ober, T., Zhang, S., Zapata-Rivera, D., Schroeder, N., & Botelho, A. (2026). Using LLMs to identify indicators of persistence from students' dialogues with a pedagogical agent. Journal of Educational Data Mining, 18(1), 208–243. Open access; supplemental materials at the OSF project doi.org/10.17605/OSF.IO/S85CK.
Hand this to anyone asking why IMPACTER's scoring pipeline uses a fine-tuned, deterministic ordinal model rather than prompting a general-purpose LLM — this ETS-lineage study documents the coding-reliability and reproducibility limits of that alternative approach.
Hirshberg, Colaianne et al. (2022) — Flourishing in College Students
Hirshberg, M. J., Colaianne, B. A., Greenberg, M. T., Inkelas, K. K., Davidson, R. J., Germano, D., Dunne, J. D., & Roeser, R. W. (2022). Can the academic and experiential study of flourishing improve flourishing in college students? A multi-university study. Mindfulness, 13(9), 2243–2256. https://doi.org/10.1007/s12671-022-01952-1. Open access via PMC.
Hand this to anyone asking for the peer-reviewed flourishing research IMPACTER cites as part of its broader research lineage on student wellbeing and reflection.
Saab et al. (2009) — NCS-1 in the Dentate Gyrus, Neuron
Saab, B. J., Georgiou, J., Nath, A., Lee, F. J., Wang, M., Michalon, A., Liu, F., Mansuy, I. M., & Roder, J. C. (2009). NCS-1 in the dentate gyrus promotes exploration, synaptic plasticity, and rapid acquisition of spatial memory. Neuron, 63(5), 643–656. https://doi.org/10.1016/j.neuron.2009.08.014. Paywalled (Elsevier) — linked to the publisher DOI record only, not rehosted.
Hand this to anyone asking about IMPACTER's stated founding inspiration: a mouse-neuroscience paper on the neurobiology of exploratory behavior, cited explicitly as lineage and never as validity evidence for the behavioral health screener.
D1 — Site Readiness Assessment (Google Doc)
The live Site Readiness Assessment tracking readiness criteria and current status by site across the six participating LEAs — IMPACTER's contribution to Deliverable 1.
Hand this to anyone asking for the current, live status of site readiness ahead of the September 30, 2026 Commission submission.
D1 — Cohort Readiness Tracker (Google Sheet)
The live Cohort Readiness Tracker recording enrollment and readiness status by school across the eighteen participating schools — IMPACTER's contribution to Deliverable 1.
Hand this to anyone asking for the current, live cohort composition and enrollment status feeding Deliverable 1.
