Standards & Readability Report

How every Studyfin lesson, quiz, and practice set is aligned to curriculum standards and written at the right reading level for the grade — automatically, and verified in code.

The five dimensions we evaluate

⭐

Curriculum — TEKS

Topics map to exact Texas Essential Knowledge & Skills student-expectation codes (e.g. 3.6(F), SCI.K.6), transcribed verbatim from the official TEA documents and injected into generation.

📘

Curriculum — CCSS

Math topics align to Common Core Math domains; English topics align to the grade's CCSS ELA-Literacy reading standards (RL/RI/RF/L).

📏

Reading level — Flesch–Kincaid

Every passage is measured with the Flesch–Kincaid Grade Level and regenerated if it reads above the grade ceiling. enforced

📖

Reading level — Studyfin Readability Index

A second, independent measure of vocabulary difficulty (the axis Flesch–Kincaid can't see), built only from public-domain methods. enforced

🌍

Global — CEFR

Each grade maps to a CEFR level (A1–C2), so content holds up to recognized international reading benchmarks, not only U.S. grade levels.

🧠

Thinking skill

Content targets the cognitive verb the standard demands (analyze, compare, evaluate…), not rote recall — with a grade-level thinking target even where no exact code applies yet.

Reading standard, by grade

Per-grade ceilings the generator enforces. PK–K are emergent (pre-reading): readability is judged on decodability and length, not scored.

Grade	Flesch–Kincaid (max)	Studyfin Readability Index	CEFR	CCSS reading codes
PK	—	emergent	Pre-A1	—
K	≤ 1	emergent	Pre-A1	5
1	≤ 2	emergent	Pre-A1	3
2	≤ 3	emergent	A2	4
3	≤ 4	520–820	A2	4
4	≤ 5.5	740–940	B1	3
5	≤ 6.5	830–1010	B1	3
6	≤ 7.5	925–1070	B1	3
7	≤ 8.5	970–1120	B2	3
8	≤ 9.5	1010–1185	B2	3
9	≤ 10.5	1050–1260	B2	3
10	≤ 11.5	1080–1335	C1	2

Curriculum alignment, by grade

Every Studyfin lesson and quiz is generated to a grade-level standard — enforced grade-level reading (Flesch–Kincaid + the Studyfin Readability Index), grade-level cognitive rigor, and a CEFR level — and aligned to TEKS and Common Core. Coverage below is the share of topics meeting that grade-level standard. (World-language is reported separately — it aligns to language-proficiency progressions.)

Grade	Topics	Grade-level aligned
PK	16	100%
K	58	100%
1	69	100%
2	91	100%
3	138	100%
4	162	100%
5	190	100%
6	193	100%
7	191	100%
8	193	100%
9	158	100%
10	146	100%
All	1605	100%

Curriculum-mapping depth: 99% of these topics are additionally mapped to an exact TEKS or CCSS student-expectation code (e.g. 3.6(F), SCI.K.6, RI.5.9) — verbatim from the official source documents, and expanding continuously. The remainder are taught to the grade-level cognitive and reading standard above.

Notes & integrity. The Studyfin Readability Index (SRI) is Studyfin's own measure, independently developed from public-domain readability methods; it is not a third-party or proprietary product and uses no licensed corpus.
