SBAC 4th grade ELA tightens the screws on inference and evidence — Part A/Part B items get harder, opinion writing now requires real source synthesis, and only 45.70% of California fourth graders are proficient.
Grade 4 ELA is where Reading-claim items get notably harder than Grade 3. The shift is in evidence selection: a Grade 3 Part A/Part B item asks 'what's the main idea?' and 'which sentence supports it?' A Grade 4 item asks the student to draw an inference (something the passage implies but does not state directly), then cite the specific phrase that signals the inference. Comparing and contrasting point of view across two texts is also new at Grade 4, as is identifying first-person versus third-person narrators. The Writing claim still uses opinion form for the Performance Task, but the prompts shift to topics that require real engagement with the sources: 'Best breakfast for a 4th grader?', 'Should computers replace teachers?', 'Recycle: yes or no?' — your child must read three actual sources and use them, not just write what they already think.
45.70% of California fourth graders scored Met or Exceeded Standard on the 2024-25 SBAC ELA — up 1.49 percentage points from Grade 3 (44.21%). ELA proficiency improves every grade through Grade 11 in California; the curve climbs as basic reading mechanics stabilize and comprehension takes over. Grade 4 is also the first year the Reading claim feels like a college-prep reading test — multi-paragraph passages with multi-part evidence items, mixed literary and informational genres, and items that punish skim-reading.
The format mirrors every SBAC grade: a Computer-Adaptive Test of 36-39 items where the engine personalizes the sequence, plus a Performance Task with three stages — Classroom Activity (teacher-led video intro, ~30 min, ungraded), Part 1 (3 sources, notes, 3 research questions, ~35 min), Part 2 (a full opinion essay using the sources, ~70 min). ETS delivers the test on the CAASPP platform; it is untimed in California.
CAASPP uses 4 achievement levels. As of the 2024-25 score reports (October 2025), the California State Board of Education renamed them: Minimal (formerly Standard Not Met), Developing (formerly Standard Nearly Met), Proficient (formerly Standard Met), and Advanced (formerly Standard Exceeded). Cut scores did not change. Proficient is the federal 'on grade level' target. Each grade has its own scale-score range; SBAC scores are vertically scaled across grades, while CAST scores are not.
SBAC's signature reporting feature is its claim-level breakdown. ELA reports four claims separately on every score report: Reading, Writing, Listening, and Research & Inquiry. Math has four claims that surface as three indicators: Concepts & Procedures, Problem Solving & Modeling/Data Analysis (claims 2 and 4 combined), and Communicating Reasoning. Each claim is flagged Above, At/Near, or Below Standard. That per-claim diagnostic is the most useful page on the score report for parents — it tells you exactly which skill to work on, not just how the child compared to a single overall cut.
Up 1.49 ppt from Grade 3 (44.21%). ELA proficiency climbs every grade — Grade 7 hits 49.65%, Grade 11 hits 56.96%.

Real SBAC format. Aligned to California Common Core State Standards for English Language Arts/Literacy. Detailed explanations on every answer.
In a story, a boy in San Francisco refuses to try dim sum because it looks "weird." His Chinese-American friend is hurt. After the boy tries it and loves it, he apologizes and asks to learn more about his friend's culture. How does the boy change?
SBAC ELA reports four claims separately at every grade — Reading, Writing, Listening, and Research & Inquiry. The Grade 4 difference vs. Grade 3 is content depth: passages are longer, inference items show up, Part A/Part B items demand specific evidence, and the opinion essay actually requires using the three sources rather than relying on the student's prior knowledge.
| Reporting Category | % of Test | What's Tested |
|---|---|---|
| Claim 1 — Reading | ~30% | Longer multi-paragraph passages, both literary and informational. Inference items (something implied but not stated), comparing/contrasting point of view across two texts, distinguishing first-person from third-person narration, vocabulary in context. |
| Claim 2 — Writing | ~25% | Opinion writing in the Performance Task essay — but the prompt now requires real source synthesis. CAT 'brief writes' include short typed responses on tone, organization, and conventions. |
| Claim 3 — Listening | ~20% | ~1-minute audio passages with rewind and pause permitted. Items test comprehension, main idea, and supporting details — same logic as the Reading claim, but with audio instead of text. |
| Claim 4 — Research & Inquiry | ~25% | Part 1 of the Performance Task: read 3 sources, take notes, answer 3 research-skill questions. Items test source-credibility evaluation, integrating information across texts, citing evidence accurately. |
| Performance Task structure (Grade 4 opinion form) | — | Classroom Activity (~30 min pre-PT, ungraded teacher-led video and discussion) → Part 1 (3 sources, notes, 3 research questions) → Part 2 (a full opinion essay using the sources). Total ~120 min, typically across two days. |
| Common text genres on the CAT | — | Literary: short stories, fables, narrative poems, dramatic excerpts. Informational: science articles, social studies pieces, biographies, how-to texts. Passage length typically runs 300-700 words at Grade 4. |
Inference is the single biggest Grade 4 ELA shift versus Grade 3. The reading items now ask 'what does the passage imply?' not just 'what does it say?' Practice at home by reading a paragraph aloud and asking your child two questions: 'What does this tell you directly?' and 'What does this make you think — that isn't actually written?' Then have them point to the specific words that triggered the inference. This is the exact Part A/Part B skill the test scores.
Practice opinion writing with real sources. The 4th-grade PT essay rewards source use and punishes opinions floating without evidence. Have your child read a short article (a one-page kids' news piece works), pick a side on a question the article raises, and write three sentences: 'I think... because the article said... For example...' The structure is the skill; vary the topic.
Use the free CDE Practice and Training Tests at caaspp-elpac.org. The Part A/Part B item type, the hot-text passage-highlighting tool, and the multi-source reading interface are all easier after 30 minutes of familiarization. The Practice Test interface is identical to test-day; the only difference is the items aren't scored.
Make sure your child can type at a reasonable pace. The Part 2 essay window is 70 minutes for a multi-paragraph piece. A child who types 10-15 words per minute will finish; a child who hunts and pecks at 5 words per minute is taking a typing test, not a writing test. Free programs like Typing.com give 10-15 minutes of practice a day and add up fast through the school year.
Read informational texts at home, not just fiction. The CAT splits roughly 50/50 between literary and informational passages, and many fourth graders read only fiction at home. Short kids' news articles (Newsela, DOGOnews, Time for Kids) or kids' science magazines (Highlights, National Geographic Kids) build the informational-text muscle the test rewards.
Four claims reported separately: Reading (longer passages, mixed literary and informational, with inference and Part A/Part B evidence items), Writing (an opinion essay in the Performance Task that requires real source synthesis, plus 'brief writes' on the CAT), Listening (~1-minute audio passages with comprehension questions), and Research & Inquiry (3-source synthesis in Part 1 of the PT). The CAT runs 36-39 items; the PT is 4 items split across two days.
Opinion writing — the same form as Grade 3, but with prompts that require actually using the three sources, not just writing what your child already thinks. Real released prompts include 'Best breakfast for a 4th grader?', 'Should computers replace teachers?', and 'Recycle: yes or no?' Your child must take a position, cite evidence from at least two of the three sources, and write a multi-paragraph essay. The rubric scores purpose, organization, evidence use, language, and conventions.
ETS-trained human raters score the Performance Task essay against a 4-point opinion-writing rubric covering five traits: purpose (clear position?), organization (intro, body, conclusion?), evidence (do they use the sources?), language (varied sentences, precise vocabulary?), and conventions (grammar, spelling, punctuation). Raters look for evidence from at least two of the three sources — a strong opinion essay without source use ceilings at a lower rubric score. Auto-scoring assists for routine items, but the essay itself is human-rated.
CDE estimates about 3.5 hours total — 90 minutes for the Computer-Adaptive Test and 120 minutes for the Performance Task (split across two days by design). The test is untimed in California: schools schedule sessions but students may take as long as the school day allows. No countdown clock on the screen.
A three-stage opinion-writing task. Stage 1 — Classroom Activity (~30 minutes, ungraded teacher-led video and discussion). Stage 2 — Part 1 (~35 minutes): your child reads three sources (a mix of articles, infographics, and short stories), takes notes, and answers three research-skill items. Stage 3 — Part 2 (~70 minutes): your child writes a multi-paragraph opinion essay using the sources. Total ~120 minutes split across two days.
Passages are 300-700 words, at the Grade 4 Lexile band. Roughly half are literary (short stories, fables, dramatic excerpts, narrative poems) and half are informational (science articles, biographies, how-to texts, social studies). Following each passage are 3-6 items: a mix of multiple-choice, Part A/Part B evidence pairs, hot-text passage-highlighting, and short typed responses. Inference items first show up in volume at Grade 4.
Three priorities. First, practice using sources — show your child how to underline a phrase in one source and rewrite the same idea in their own words, then connect it to a position they're taking. The 4th-grade PT essay penalizes opinion essays that ignore the provided sources. Second, build the essay structure as muscle memory: introduction with a clear opinion → body paragraphs with reasons and source evidence → conclusion. Third, type at a reasonable pace — the essay is typed, not handwritten.
45.70% of California fourth graders scored Met or Exceeded Standard (the new 'Proficient' label) on the 2024-25 SBAC ELA, per CDE's October 2025 release. Up 1.49 percentage points from Grade 3. ELA proficiency improves every grade through Grade 11 in California — Grade 7 hits 49.65%, Grade 11 hits 56.96% — as basic reading mechanics stabilize and comprehension takes over.
2,140 to 2,690 on the Grade 4 SBAC ELA scale. Cut scores: Minimal/Standard Not Met (up to 2,415), Developing/Standard Nearly Met (2,416-2,472), Proficient/Standard Met (2,473-2,532), Advanced/Standard Exceeded (2,533 and up). The State Board of Education renamed the four levels in March 2025; cut scores didn't change. SBAC ELA scores are vertically scaled, meaning a 2,500 in Grade 4 represents the same achievement on the underlying scale as a 2,500 anywhere else.
Only as an accommodation, not as a universal tool. Text-to-speech for ELA reading passages requires an IEP or 504 plan documenting the need. (TTS for math items is more broadly available as a designated support; ELA passages are protected because reading them is what's being assessed.) The Listening claim's audio passages ARE played for every student — those are pre-recorded and run through the headphones every test-taker uses. Rewind and pause are permitted on audio items.
