Healthcare.pdf — representative release (v1.0)

A PDF-grounding benchmark for healthcare document work: 25 expert-authored tasks grounded in 25 real healthcare documents, covering 7 occupations across clinical and pharmacy practice.

Each task puts a practitioner in a realistic situation, gives them a real document, and asks a sequence of sub-questions that must be answered from that document. Answers are graded against a four-tier rubric.

Tasks	25
Source documents	25 (CDC Stacks, FDA drug labels)
Sub-questions	152
Rubric criteria	1,513
Occupations	7
Document pages	350

Fields

Field	Description
task_id	persona/occupation/task_id
persona, occupation, aspect	role and the workflow area the task belongs to
doc_id, document_name, document_file, doc_pages	source document identity
document	the source PDF
case_setup	the clinical/pharmacy situation the practitioner is in
sub_questions	list of {q_no, question, reference_answer, task_types, anchor_ids, derivation, premises_grounded}
anchors	list of {id, element_type, title, locator_quote, page, answer_bearing} — the document locations the task is grounded in; sub_questions.anchor_ids and rubric.source_anchor_id resolve against these
rubric	list of {rubric_id, q_no, tier, grading_mode, kind, criterion, source_type, source_anchor_id, task_types}
n_subquestions, n_criteria	counts
difficulty_band, n_models_solved, n_models_all_criteria	observed difficulty (see below)

Rubric tiers

• G1 Domain — healthcare-wide conformance (grounding, citation, no fabrication)
• G2 Persona — expectations for the persona
• G3 Occupation — expectations for the specific occupation
• G4 Task — the task's own content criteria, graded per sub-question

grading_mode is match (the answer must state this value), entailed (the answer must imply this step), or present (a behaviour/format requirement over the whole deliverable).

Task types

Sub-questions are tagged with a capability taxonomy (T1–T19) spanning foundational extraction (value extraction, layout navigation), structural reading (table parsing, conditional logic), advanced reasoning (abstention, quantitative reasoning, synthesis) and healthcare-specific work (clinical safety, care-transition extraction, eligibility matching). All 18 types present in the source pool are represented here.

Difficulty

difficulty_band records how many of six frontier models solved each task, under a two-grader consensus. A task is solved when every sub-question conveys the reference answer's key value or conclusion.

Band	Models solving	Tasks
unsolved	0 / 6	6
hard	1–2 / 6	5
mid	3–4 / 6	6
easy	5 / 6	4
ceiling	6 / 6	4

n_models_all_criteria is a stricter reading — how many models passed every rubric criterion, not just conveyed the right answers. Across the release that is 8 of 150 model-task pairs versus 72 of 150 for solved. The gap is the point: most answers that look right still miss rubric criteria.

The hard end is deliberately over-sampled relative to the source pool, so this subset is harder than the full benchmark and its absolute scores should not be read as corpus-wide performance.

Source data

• CDC Stacks (14 documents) — US public-domain government publications
• FDA drug labels (11 documents) — US public-domain regulatory documents

Documents were selected for containing determinate, answer-bearing content that a practitioner would act on. Tasks and rubrics were authored against those documents and anchored to specific locations within them.

This release is the redistributable portion of a larger benchmark. A third track built on MIMIC-IV radiology reports is not included: PhysioNet credentialed access forbids redistribution.

Selection

The 25 were chosen from a 100-task redistributable pool to span difficulty, occupation and capability while preserving the pool's model ranking (Spearman ρ = 0.956, no inversions among separable model pairs). Rank fidelity was an explicit selection objective, so it is a design property rather than independent evidence. One task per source document; at most two tasks per workflow aspect.

Limitations

• Not a random sample. Deliberately over-weighted toward hard tasks; not an estimate of corpus-wide difficulty.
• Two personas only. Generalist clinicians (14) and pharmacists (11); the specialist track is excluded for licensing.
• Answer keys are public. Reference answers and rubrics ship with the tasks, so results are only meaningful for models that have not trained on this data. Treat it as a one-shot measurement and report the model's training cutoff.
• Expert review is partial. 6 of the 25 tasks were audited by practising clinicians as part of a broader purposive review; the remainder were not individually SME-reviewed.
• Grader-dependent. Difficulty metadata comes from LLM graders (two independent vendors, consensus required). Grader choice moves absolute numbers.
