If you (or your students) are preparing for the CASAS STEPS Reading Level D test, this guide breaks down the four content areas, how often each appears, and strategies to answer them successfully. Level D is designed for high-intermediate learners (ESOL 4–5), moving beyond the simpler forms and short ads of Levels B and C. At this stage, texts become longer and more detailed: job ads list multiple conditions, workplace memos include several instructions, and emails may mention more than one person or event. Vocabulary items also expand to include academic words and words with multiple meanings.
According to the official CASAS STEPS blueprint, Level D balances Details and Main Idea (each 30%), while adding a significant share of Inference (18%). This reflects the shift toward higher comprehension skills—students must not only find facts, but also evaluate purpose, point of view, and implied meaning.

Blueprint for CASAS STEPS Reading Level D
Here is the official distribution of content areas for CASAS Level D Reading. Notice that Details and Main Idea together make up 60% of the test, while Vocabulary and Inference also carry significant weight.
Vocabulary
What changes at CASAS STEPS Reading Level D: Vocabulary items expand into academic and workplace terms as well as words with multiple meanings. Learners must not only know definitions, but also interpret the correct meaning in context.
Example: From a dental job ad: “Duties include … document patient health history.”
Tips: Encourage students to test each option in the sentence. The correct choice should fit both grammatically and logically.
Details
What’s most important: With nearly one-third of the test, detail questions in a CASAS STEPS Reading Level D test require students to find exact information such as dates, requirements, times, or conditions. Distractors often include realistic but incorrect options.
Example: From a class notice: “What is required to take the class? Access to a computer at home. Must be 18 or older.”
Tips: Train learners to read the question first, circle the keyword (date, fee, requirement), and scan for only that piece of information.
Main Idea
What changes at Level D: Main idea and purpose questions in CASAS STEPS Reading Level D occur in longer passages like workplace emails, memos, or travel notices. Students must move beyond small details to capture the overall message or author’s point of view.
Example: From a company email: “Due to increased travel costs, we are changing some of our business travel policies beginning today …”
Tips: Remind learners that the main idea covers the whole passage, not just one line. Look for repeated words or the stated reason.
Inference
Why this matters: Inference questions in CASAS STEPS Reading Level D rise to almost one-fifth of Level D. Learners must decide what is most likely true based on clues, even if the text doesn’t say it directly. This tests higher-level comprehension and reasoning.
Example: From a workplace leave email: “I talked to Isaiah Moran … He said he would gladly help out while you are gone. Please meet with him before you leave. He’s not prepared as of today.”
Tips: Teach learners to cross out answers that contradict the text. The correct inference will not invent new ideas, but instead connect logically to the passage.
General Tips:
- Always read the question first, then skim the text for the answer.
- Underline or circle names, numbers, and conditions—these are frequent distractors.
- For main idea, ask: “Why was this written?” not “What is one detail?”
- For inference, focus on what is suggested, even if not stated directly.
- Practice with authentic materials: job ads, forms, workplace emails, memos, and policies.
