CASAS common mistakes
CASAS · Understand the traps and how to avoid them.
When a recorded dialogue is played only once, the candidate stops listening to answer the first question, then misses the next two items because the audio keeps moving.
CASAS listening tasks are paced by the recording, not the test-taker; candidates trained on self-paced practice try to answer item-by-item in real time.
What to do instead
Practice with audio played exactly once and no pause button. Before playing, read the answer choices to predict what to listen for (a time, a price, a name). Mark a best guess immediately after each question and move on; never return to re-listen mentally while new audio plays.
The candidate answers a 'what will she do next' or 'what does this notice mean' item with a detail that was stated, instead of the inference the question asks for.
Under time pressure, matching a word from the audio or text to an answer choice feels safe, so literal matching replaces the actual question stem.
What to do instead
Underline or say the question word first: what, why, when, how much, what next. Eliminate choices that merely repeat a stated word but do not answer that word. For 'next' items, ask what action logically follows the last thing said.
On a form or utility-bill item, the candidate reads the whole page line by line and runs out of time before reaching the questions.
School reading habits reward full comprehension; CASAS consumer documents are scanned for a specific field, and candidates do not switch to search reading.
What to do instead
Practice locating one field at a time: find the account number, then the due date, then the late fee. Use headings, bold labels, and column positions as guides. Time yourself to 60-90 seconds per document set and skip anything requiring a full read.
The candidate computes a total, discount, or unit price correctly but selects the wrong answer because they did not check which unit or rounding the choices use.
Computation items embed the arithmetic in a real context (price per pound, hours on a time card), and candidates stop at the raw number.
What to do instead
After computing, restate the question in your own words ('cost for 3 pounds, not 1'), then compare the magnitude of your answer to the choices. If your result is not listed, check for a unit conversion or a two-step operation you skipped.
The candidate misreads a medical label or appointment slip by ignoring frequency words such as 'every 6 hours', 'twice daily', or 'take with food'.
Health documents combine numbers with abbreviated instructions; candidates focus on the dosage number and skim the directions.
What to do instead
Read health instructions aloud in a fixed order: what, how much, how often, how long, and any warning. Convert frequency into a daily total to confirm it makes sense, and flag any choice that changes the timing or the maximum daily dose.
On an employment item, the candidate confuses gross pay with net pay, or regular hours with overtime hours, when reading a pay stub or job posting.
Pay stubs present many similar-looking numbers in adjacent columns, and candidates grab the largest or boldest figure.
What to do instead
Label each figure before answering: gross, deductions, net, regular rate, overtime rate. For job postings, separate required qualifications from preferred ones. Practice with sample pay stubs until the column layout is familiar.
The candidate answers a government or law item from personal opinion or general knowledge instead of the passage, form, or scenario provided.
Topics like voting, taxes, or permits invite outside assumptions, and candidates answer what they believe rather than what the text states.
What to do instead
Treat every item as evidence-based: point to the line or field that supports the answer. If two choices seem true in real life, choose the one the document actually says. Review common document types (registration forms, notices, jury summons, lease clauses) so the vocabulary is familiar.
The candidate misses community-resource items that require matching a need to the right agency, such as choosing a library for internet access or a county office for a permit.
Candidates know the service exists but not which organization provides it, and answer choices are all plausible-sounding offices.
What to do instead
Build a short mental map: library (books, computers, classes), post office (mail, passports), city or county clerk (permits, records), social services (benefits), clinic (health). For each practice item, name the need first, then the provider, then verify against the description given.
The candidate skips or misreads directions on a section that changes format, such as switching from multiple choice to filling in a blank or choosing 'all that apply'.
CASAS sections vary in response format, and candidates who rush into the first item carry the previous section's habits forward.
What to do instead
Read the section directions before the first item, and note the response type on scratch paper. On 'choose all that apply' items, count your selections and re-check whether any unselected option also fits. Budget a few seconds per section for this reset.
The candidate spends too long on one hard item and leaves later, easier items blank, lowering the score more than the hard item was worth.
Without a pacing plan, a single confusing document or audio item consumes minutes, and candidates do not realize the cost until time is nearly gone.
What to do instead
Set a per-item cap (about one minute for reading items) and a hard stop: mark a guess, flag it mentally, and move on. At the end, return only to flagged items with time remaining. Practice full-length timed sets so the pacing habit is automatic.
