CASAS vs TABE 2026: How the Two Adult-Education Tests Differ, What Scores Mean, and Which One to Use

CASAS vs TABE 2026: The Direct Answer

Both CASAS and TABE are federally recognized adult-education assessments used to place learners, measure learning gains, and report progress under the National Reporting System (NRS) inside WIOA-funded Adult Basic Education (ABE), Adult Secondary Education (ASE), and English as a Second Language (ESL) programs. Neither one is a credential exam, and neither has a single national passing score. The short answer for most people choosing between them in 2026:

• You usually do not pick the test — your program does. Your state agency approves a list, and your school, workforce center, or correctional/adult-ed program selects one. Programs generally cannot switch a learner between CASAS and TABE in the same program year.
• CASAS leans toward functional, real-life skills (paychecks, bills, schedules, forms, labels) and offers a dedicated Listening test for ESL — useful for English learners and life-skills-focused programs.
• TABE leans toward academic/computational skills (reading, mathematics, language mechanics) and is the test many programs use when the goal is GED or HiSET readiness and college-and-career-readiness routing.
• The numbers are not interchangeable. A CASAS scale score and a TABE scale score live on completely different scales, so a "good CASAS score" tells you nothing about a TABE level and vice versa. You read each one against the NRS Educational Functioning Levels (EFLs).

Quick comparison: CASAS vs TABE at a glance

The single most important row is the last one. People search "what score do I need to pass CASAS" or "TABE passing score" expecting one number. There isn't one for either test. What matters is the NRS Educational Functioning Level your score lands in, and what your program does with that level.

Are both tests "official"? Yes — both are NRS-approved

This is the question that trips up many learners and even new program staff. Both CASAS and TABE are listed by the U.S. Department of Education as tests determined suitable for use in the National Reporting System for Adult Education. The Department's Federal Register notice on NRS-suitable tests names both the TABE 11&12 forms and the CASAS GOALS reading and math series among approved instruments, with stated approval windows. The current CASAS ESL series (Reading STEPS and Listening STEPS) are NRS-approved for English learners as well.

What this means in practice:

• Neither test is "better" in the eyes of the federal government. Both produce NRS-reportable educational gains when administered to the right population.
• Your state narrows the federal list, and your program picks from the state list. That is why a neighboring city may use a different test than yours.
• Approval is time-limited and forms get retired. Older CASAS Life and Work forms have been replaced by GOALS 2 and STEPS, and TABE 9&10 was replaced by TABE 11&12. If you find an old conversion chart online, confirm it matches your current test version before trusting any number.

For official program rules, always confirm with the CASAS WIOA/NRS approval page and the TABE 11&12 publisher site (DRC) — and ultimately with your state's adult-education assessment policy.

When to use CASAS vs when to use TABE

Program staff weigh several factors. Learners benefit from understanding them because it explains the test they were given.

CASAS tends to fit when:

• The program serves many ESL/English-learner students and needs a dedicated listening measure (Listening STEPS) plus functional reading (Reading STEPS).
• The instructional focus is life and work skills — reading a pay stub, a medicine label, a bus schedule, a workplace notice, a form, or a chart.
• Staff want shorter administration and a strong tie to functional adult-education competencies.

TABE tends to fit when:

• The program routes learners toward GED or HiSET and wants an official TABE-to-HSE concordance that predicts readiness in Reading, Math, and Language.
• The curriculum is more academic and computational (algebra, geometry, language mechanics) rather than purely functional.
• Staff want a separate Language subtest covering grammar, usage, sentence structure, and writing conventions, which TABE includes and the core CASAS academic series does not isolate the same way.

A practitioner rule of thumb that shows up repeatedly in adult-education discussions: CASAS math sits at a lower computational level and emphasizes comprehension and application, while TABE is more computation- and academic-skills heavy. Both are valid — the right choice depends on the learner population and the program's exit goals.

Reading the scores: CASAS scale scores and NRS levels

CASAS reports scale scores that map to the six NRS Educational Functioning Levels. These are the official 2025 CASAS ABE/ASE ranges:

For ESL learners, CASAS uses separate STEPS ranges:

A key CASAS transition rule: an ESL learner who scores 239 or higher on Reading STEPS is ready to move from the ESL STEPS series to the academic GOALS series. So the same number — 239 — means different things on different CASAS series, which is exactly why context matters. Verify ranges on the official CASAS scale scores, NRS EFLs, and grade levels page.

Reading the scores: TABE scale scores, levels, and NRS

TABE 11&12 also reports scale scores, but on a different scale (roughly 300–800 depending on subject and level) and through level-specific forms. TABE uses five levels by difficulty:

• L (Literacy / lowest)
• E (Easy)
• M (Medium)
• D (Difficult)
• A (Advanced / highest)

No single TABE form covers every NRS level. A learner takes a Locator first, which has separate sections for reading, mathematics, and language, and the results indicate which level to administer per subject. Each form then reports a scale score that maps into NRS EFLs — and because the forms are level-targeted, the same NRS level can be reached from different forms. That is why TABE conversion is done with the current TABE 11&12 charts, not old TABE 9&10 tables.

The practical takeaway is identical to CASAS: a TABE scale score by itself is meaningless until you place it into an NRS level and ask what your program requires for placement, gain, or HSE routing.

GED / HiSET readiness: where TABE has a clear edge

If your goal is a high school equivalency diploma, this is the most decision-relevant section. DRC publishes an official TABE-to-HSE concordance that maps TABE scale scores to predicted readiness for the GED and HiSET. From the 2025 DRC concordance:

DRC frames TABE as a directional readiness predictor for each HSE test, and notes that some states even use TABE as an alternative pathway toward a high school diploma. See the official TABE to HSE concordance (DRC, 2025).

CASAS also supports HSE routing and has published GED and HiSET comparison studies, but the headline, learner-facing concordance numbers above come from TABE. If a learner's near-term objective is "am I ready to sit the GED or HiSET," a program using TABE can give a cleaner, published prediction. A program using CASAS will instead route on NRS level and local benchmarks.

Important: passing TABE's "minimum HSE" band is a predictor, not the GED/HiSET itself. You still have to take and pass the actual high school equivalency exam to earn the credential.

ESL placement: where CASAS often wins

For English learners, CASAS offers a purpose-built ESL pathway: Reading STEPS for functional English reading and Listening STEPS for everyday and workplace listening, each aligned to English-language-proficiency standards across six NRS ESL levels. The dedicated listening measure is meaningful because spoken-English comprehension is central to early ESL progress and is hard to capture with a reading-only test.

TABE's core 11&12 battery is built around academic Reading, Mathematics, and Language and does not include a standalone ESL listening assessment in the same way. Programs that need to document listening gains for English learners frequently choose CASAS (or pair an academic test with a separate approved ESL listening instrument, depending on state rules). If you are an English learner placed into a STEPS test, that is usually a deliberate fit, not a mistake.

Cost, delivery, and logistics differences

Both tests are administered by trained program staff, not bought and self-proctored by individuals, so you generally will not pay a personal exam fee the way you would for a licensing exam. The differences that matter:

• Delivery: Both offer online and paper. TABE Online runs on DRC INSIGHT; CASAS uses CASAS eTests. Online delivery is faster to score and reduces paper handling for both.
• Materials and scoring: Paper administrations require purchased test booklets and answer keys (for example, paper TABE answer keys carry a per-key cost plus shipping). Online delivery typically scores automatically.
• Calculators and tools: TABE math at certain levels permits a basic four-function calculator on designated sections; follow the exact administration manual for your level. CASAS functional math is built around real-life computation and follows CASAS administration rules.
• Accommodations: Both publishers support accessibility (large print, Braille, audio for TABE; CASAS accommodations through its guidance). Arrange accommodations through your program in advance.
• Retesting: Both tests are designed to document learning gains, so retesting is expected after instruction (a pretest, then a post-test). Re-sitting immediately without instruction is not how either test is meant to work.

Because exact prices, forms, and approval windows change, confirm logistics with your program and the official publisher pages rather than a third-party chart.

Common confusions about CASAS vs TABE

"Which one is the GED test?" Neither. Both are placement/progress assessments. The GED and HiSET are the actual high school equivalency credential exams; CASAS and TABE only help measure readiness and progress.

"My friend scored 240 — is that good?" You cannot compare across tests. 240 on a CASAS series and 240 on TABE are different scales. Even within CASAS, 239 means "exit ESL / High Adult Secondary reading" on one series but something else on another.

"Can I choose CASAS instead of TABE?" Usually not as an individual. The program (constrained by the state list) chooses, and switching tests mid-year for the same learner is generally not allowed.

"Is a higher level always the goal?" The goal is an accurate level for placement plus a documented gain between pretest and post-test. The locator/appraisal exists to put you on the right level so the result is meaningful — not artificially easy or hard.

"Are old conversion charts fine?" No. Use current TABE 11&12 and current CASAS GOALS 2 / STEPS charts. TABE 9&10 and older CASAS Life and Work numbers do not map cleanly to the current series.

How to prepare once you know your test

The study approach differs slightly by test, but the engine is the same: practice the question style, then convert every mistake into a specific fix.

• If you are on CASAS, drill functional documents — pay stubs (gross vs. net), unit price, schedules, labels, forms, and charts — plus listening for ESL learners. Use CASAS practice questions and the CASAS study guide.
• If you are on TABE, balance reading comprehension, applied and computational math, and the Language subtest (grammar, usage, mechanics). Use TABE practice questions for mixed, level-appropriate repetition.
• Either way, track your starting NRS level, set a target for your post-test, and tag every missed item by cause (missed detail, wrong operation, unit error, grammar rule, listening detail) so your next study block repairs the real gap.

Official resources

Use official and authoritative sources for any number that affects placement, scoring, reporting, or HSE routing:

• Federal Register — tests suitable for the NRS (U.S. Dept. of Education) — the federal list naming TABE 11&12 and CASAS series.
• CASAS WIOA/NRS approval page — current CASAS approval status and reporting rules.
• CASAS scale scores, NRS EFLs, and grade levels — official CASAS-to-NRS score ranges.
• TABE 11&12 publisher site (DRC) — TABE subjects, levels, locator, and delivery.
• TABE to HSE concordance (DRC, 2025) — TABE Reading/Math scores mapped to GED and HiSET readiness.
• National Reporting System for Adult Education — the federal accountability system both tests report into.

Bottom line

CASAS and TABE are both legitimate, NRS-approved adult-education assessments, so the real decision is fit, not legitimacy. Choose (or understand) CASAS for functional, life-and-work skills and a dedicated ESL listening measure; understand TABE when the destination is GED or HiSET and a published readiness concordance helps. Read every result against the NRS Educational Functioning Level, never as a stand-alone "pass" number, and verify ranges against the current official charts because the two scales do not translate to each other. Then prepare for the specific test your program assigned and aim for a documented gain — that is what both systems are actually designed to reward.
