ADVERSARIALLY AUDITED

🌳 AcornSmarts × Missouri Standards — Grades 9–12 Alignment Report

Generated 2026-09-16 · State: MO · Standards scope: high-school mathematics (Algebra I, Geometry, Algebra II EOC expectations) + grades 9–12 English Language Arts · Rebuilt from the audited crosswalk data on each revision.

The grades 9–12 stage (the $99/yr High School plan) went live in AcornSmarts on 16 September 2026. The K–5 and 6–8 reports for Missouri are published separately at acornsmarts.com/standards/.

How to read this report (the honest version). Every row below is a single published Missouri high-school standard code and the verdict our own audit gives it. FULL = live question families directly exercise every clause of the code. PARTIAL = a real component is exercised and the missing clause is named in the gap column. NOT COVERED = we make no claim, listed as plainly as the coverage. Across Missouri's 225 assessed codes the counts are 16 FULL · 134 PARTIAL · 75 NOT COVERED — AcornSmarts at the high-school level is a practice supplement with deliberately broad-PARTIAL verdicts, not a course, and this page says so before anything else does. Verdict provenance: a 41-agent adversarial alignment run (2026-09-16) over the shipped question generators, consistency-corrected so a cluster is never credited above its own children. Biology and Government standards are excluded by design (labs and civics discussion cannot be honestly claimed by an app) and are not counted anywhere on this page. Codes are exact; the standard statements themselves are in the official Missouri standards documents.

A1.NQ.A PARTIAL oak-exponentials:L2
"Write with a rational exponent: ∛(5^2)" and "2^(1/2) · 2^(1/2) = ?" — properties used and meaning extended

▶ Play a live item from this skill
CONSISTENCY: Cluster head credited FULL from the same oak-exponentials:L2 bank as its children, and child A1.NQ.A.1 establishes the 'explain how the meaning extends' clause is never the judged demand (rationale-only). A cluster cannot be FULL while a component child is PARTIAL on the same bank — shared-bank cap plus internal contradiction.
A1.NQ.A.1 PARTIAL oak-exponentials:L2
"2^(1/2) · 2^(1/2) = ?" exercises the extension computationally; the explanation lives only in the why-string

▶ Play a live item from this skill
'Explain how the meaning extends' is never the judged demand — items compute; the reasoning is rationale-only.
A1.NQ.A.2 FULL oak-exponentials:L2
"Write with a rational exponent: √(5)", "∛(7^2)" — direct radical↔rational-exponent rewriting, within the limit

▶ Play a live item from this skill
A1.NQ.B NOT COVERED
No served algebra-1 item asks for unit identification, labeling, conversion, or scale/origin choice
Entire cluster: no units-of-measure items exist in any served level.
A1.NQ.B.3 NOT COVERED
No item converts units or rates or interprets scale/origin; plan-cost items use $ only as narrative dressing
All four sub-clauses (label, convert, use, scale/origin) unserved.
A1.NQ.B.4 PARTIAL oak-linear-equations:L2
"A plan costs a $40 signup fee plus $8 per month... Which equation models the months m?" — quantities used in context

▶ Play a live item from this skill
Students never DEFINE or choose the quantities — the variable and quantities are handed to them; only 'use' is exercised.
A1.NQ.B.5 NOT COVERED
No served item involves measurement, rounding, or accuracy/precision decisions of any kind
Accuracy-appropriate-to-measurement is entirely absent.
A1.SSE.A PARTIAL oak-functions:L4 + oak-quadratics:L2/L4
"What does the 50 represent?" (interpret) and "Factor: x² + 9x + 18" / "Complete the square..." (use structure)

▶ Play a live item from this skill
CONSISTENCY: Cluster FULL rides the identical oak-functions:L4 + oak-quadratics banks credited to children A.1/A.2/A.3, all of which land PARTIAL (factors-clause never judged; max/min value never asked). Shared-bank cap and contradiction with its own components.
A1.SSE.A.1 PARTIAL oak-functions:L4
"C(h) = 14h + 50... What does the 50 represent?" — only the constant term is ever the asked target

▶ Play a live item from this skill
Coefficient/factor interpretation appears only as distractors and why-strings; 'factors' clause never the judged demand.
A1.SSE.A.2 PARTIAL oak-quadratics:L1/L2
"(x + 5)(x + 2) = ?" and "Factor: x² − 2x − 15" — equivalent polynomial forms produced both directions

▶ Play a live item from this skill
CONSISTENCY: Cross-state twin of KS A.SSE.2 (same CCSS 'use structure to rewrite' content, same oak-quadratics bank). KS auditor found monic-trinomial factoring only — no difference of squares, no grouping — and a shared bank with A.SSE.3a. Wording does not genuinely differ; stricter reading wins.
A1.SSE.A.3 PARTIAL oak-quadratics:L3/L4
"What are the zeros of f(x) = x² − 11x + 28?" and "Complete the square: x² − 8x + 14 in vertex form"

▶ Play a live item from this skill
Clause (b)'s max/min VALUE is never asked — items stop at vertex form; the vertex/minimum reading is rationale-only, and 'explain properties' is unjudged.
A1.CED.A PARTIAL oak-linear-equations:L2 + oak-exponentials:L5
Linear ("Which equation models the months m?") and exponential ("Which equation models it?") creation served; quadratic absent

A1.CED.A.3 NOT COVERED
"Which point satisfies y > 3x + 4?" — point-as-solution/non-solution of an inequality, but context-free
No modeling context (rule 7): constraints are bare inequalities, never represented FROM a scenario, and systems of inequalities are absent. | CONSISTENCY: Twin of KS A.CED.3 (NOT COVERED). Both auditors agree the only related item is a context-free 'Which point satisfies y > 3x + 4?' with no constraint represented FROM a scenario and no viability judgment. Under the audit's own rule 7 (modeling clause needs a contextual item), the bare point-check serves nothing of this standard.

▶ Play a live item from this skill
Congruence exercised via SSS/SAS/ASA recognition only; no served item connects congruence to rigid motions.

CODES ASSESSED
ELA scope note (honest by construction): AcornSmarts assesses reading comprehension at adult register, language conventions, and machine-judged analytical/argument/informative writing. The speaking & listening strand, collaborative discussion, multi-source research projects, and full-length process essays are NOT COVERED by design — an app cannot honestly claim them — and they are listed plainly below.

'Which quotation BEST supports the claim that the speaker was demoted rather than developed?'; 'never states his overall position...read between the lines'

▶ Play a live item from this skill

Visual-element interpretation absent from the served bank
11-12.RL.1.D PARTIAL oak-reading-2:L1
"Which TWO central ideas do the paired texts develop, taken together?"

▶ Play a live item from this skill

"The speech is structured as a gratitude list. Why is this structure the right delivery system for its actual content?"

▶ Play a live item from this skill
Structure-to-meaning demand is exercised, but on a nonfiction speech, not literature; aesthetic-impact clause thin; shared bank across distinct standards.
11-12.RL.2.B PARTIAL oak-reading-2:L1
"The speaker says he is 'grateful' throughout. What is really being communicated?"

▶ Play a live item from this skill
Stated-vs-implied is directly exercised but on a speech rather than a literary text; same shared bank serves the parallel RI code.
11-12.RL.2.C PARTIAL oak-reading-2:L1
"'They do not compress; they staff.' Evaluate how this sentence's construction serves Text B's argument."

▶ Play a live item from this skill
Word-choice and syntax items exist ('performative presence', extended metaphor) but on nonfiction; tone/aesthetic-impact of literature untested; shared bank.

Element-relation is exercised only at sentence/structure level of a speech; no development-of-literary-elements (character, setting, plot) items; shared bank.
11-12.RL.3.A NOT COVERED
No served item presents a subject in two artistic mediums; bank is two written texts on one topic.
No cross-medium (film/art/audio vs text) comparison item exists anywhere in oak-reading-2.
11-12.RL.3.B PARTIAL oak-reading-2:L1
"Synthesizing both texts: what is the most complete account of the four-day week's prospects?"

"The speech assumes an employment world of corner-office promises, decades-long tenure... What perspective does the author write FROM?"

▶ Play a live item from this skill
One perspective item on a nonfiction speech; no literary work evaluated against its historical/cultural context; shared bank.
11-12.RL.3.D NOT COVERED
oak-reading-2 serves no story, drama, or poem at any level; both texts are workplace nonfiction.
Independent, proficient reading of literature (stories, dramas, poems) has zero serving items.
11-12.RI.1.A PARTIAL oak-reading-2:L1
"Which quotation BEST supports the claim that the speaker was demoted rather than developed?"

Context and figurative meaning (extended metaphor) exercised; affixes/reference-materials strategies absent; two vocabulary items in a shared bank.
11-12.RI.1.C NOT COVERED

11-12.RI.2.A PARTIAL oak-reading-2:L1
"The speech is structured as a gratitude list. Why is this structure the right delivery system for its actual content?"

▶ Play a live item from this skill
Structure-to-meaning fits the informational texts well, but the identical items are credited to RL.2.A — shared bank caps at PARTIAL; aesthetic-impact clause thin.
11-12.RI.2.B PARTIAL oak-reading-2:L1
"Text B's author never states his overall position on the four-day week. What is it, read between the lines?"

▶ Play a live item from this skill
Direct hit on non-obvious POV in informational text, but the same items also serve RL.2.B — shared-bank cap; only one text set exercises it.
11-12.RI.2.C PARTIAL oak-reading-2:L1-L3
'They do not compress; they staff.' Evaluate how this sentence's construction serves Text B's argument.

▶ Play a live item from this skill
Strong syntax/word-choice items, but a single 12-item paired-text bank is reused verbatim across L1-L3 and credited to multiple distinct RI standards — shared-bank cap; no range of texts for tone evaluation.
11-12.RI.2.D PARTIAL oak-reading-2:L1-L3
'Evaluate Text B's reasoning. What makes its selection-bias argument strong?'

▶ Play a live item from this skill
Argument/evidence-validity items exist, but same shared bank serves several standards (cap); credibility and relevance-of-evidence clauses touched only via one selection-bias item on one text pair.
11-12.RI.3.A NOT COVERED
All served pairs are print texts (a speech transcript and an article); no item presents a second artistic medium.
No two-medium comparison — no visual, audio, film, or performance treatment of a subject is served; standard requires two different artistic mediums.
11-12.RI.3.B PARTIAL oak-reading-2:L1-L3
'Synthesizing both texts: what is the most complete account of the four-day week's prospects?'

▶ Play a live item from this skill
Genuine two-text synthesis items exist, but only one text pair and a shared bank credited to multiple standards — shared-bank cap; 'two or more texts' variety not demonstrated beyond a single pairing.
11-12.RI.3.C PARTIAL oak-reading-2:L1-L3
'The speech assumes an employment world of corner-office promises, decades-long tenure... What perspective does the author write from?'

▶ Play a live item from this skill
One perspective item reads authorial worldview; historical/cultural framing is contemporary-workplace only, and it sits in the shared multi-standard bank (cap).
11-12.RI.3.D PARTIAL oak-reading-2:L1-L3
Twelve informational-text comprehension items served independently (e.g. 'performative presence' in context; central-ideas item).

▶ Play a live item from this skill
Comprehension is exercised, but on one paired-text set repeated identically at every level — no range or increasing complexity to evidence 'independently and proficiently' across the band.
11-12.W.1.A NOT COVERED
No wp-oak rubric line grades research, source gathering, advanced searches, or citation; no served item involves sources.
'Conduct research' is a conduct wall and nothing served even approaches its knowledge core — no source-evaluation, inquiry-narrowing, or citation-system content anywhere.
11-12.W.2.A PARTIAL wp-oak-argument / wp-oak-analyze / wp-oak-inform
wp-oak-argument rubric: 'A precise, arguable claim... Formal register maintained... A conclusion that follows from the argument'
Judged essays grade development, organization, style and audience-appropriate register across three modes, but 'follow a writing process' is a process clause the single-draft rubric cannot grade — process cap; 'blend techniques' is not graded either.
11-12.W.3.A PARTIAL wp-oak (rubrics) + oak-language:L1
'Which is the MOST CONCISE revision of: "due to the fact that the bridge was closed"?'
Revision exists only as recognition items (conciseness, transitions) and as rubric lines on a first-draft essay; no review-revise-edit cycle on the student's own writing is served — multi-draft clause capped.
11-12.SL.1.A NOT COVERED
No served item or rubric involves peer discussion, goals/deadlines, or role assignment.
Collaborative-discussion conduct standard; a single-learner item platform serves nothing toward it, including its knowledge core.
11-12.SL.1.B PARTIAL oak-reading-2:L1-L3
'Which quotation BEST supports the claim that the speaker was demoted rather than developed?' (retirement speech)

▶ Play a live item from this skill
Items delineate a speaker's argument, stance and evidence from a speech text — the knowledge core — but the conversation clauses (posing/responding to questions, ensuring a hearing, propelling discussion) are conduct and unserved; capped.
11-12.SL.1.C PARTIAL oak-reading-2:L1-L3
'Which TWO central ideas do the paired texts develop, taken together?'

▶ Play a live item from this skill
Synthesis-across-perspectives items exercise the knowledge core in reading form only; responding in discussion, qualifying one's own views, and diverse-media inputs are conduct clauses with no served counterpart — capped.
11-12.SL.2.A NOT COVERED
No served item addresses speaking, articulation, volume, pitch or pace.
Oral-delivery performance wall; nothing in reading, language or writing banks touches its knowledge core.
11-12.SL.2.B NOT COVERED
No served item addresses eye contact, gesture, or physical delivery.
Pure performance standard; no served counterpart of any kind.
11-12.SL.2.C NOT COVERED
No served item or rubric involves planning or delivering a presentation or using multimedia.
Plan-and-deliver-with-multimedia is a production/conduct wall; no recognition item about presentation craft exists either.

What this program deliberately does not claim

The recurring walls, named once so no verdict has to hide them: proof-writing and formal derivations (we assess the computation and the justification-selection half); freehand construction and graph production (we assess reading and interpreting, not drawing); conducting real experiments, surveys, and simulations; units-of-measure modeling choices in multi-step real-world set-ups; the entire speaking & listening strand; multi-source research projects; and full-length process essays (our Writing Coach judges short constructed responses against named rubrics). Codes built on those verbs appear above as NOT COVERED or with the limitation named in their gap column.
