Free NCCER Core Practice Test & Study Guide
Preparing for NCCER Core gets a lot easier once you separate the full Core curriculum from the current Core Level Test. The broader Sixth Edition catalog contains 10 modules. The current Level Test specification covers eight of them in an 89-question, three-hour, closed-book test with a 70 percent minimum passing score.
Current Core Level Test at a glance
The current specification describes the test as closed book and allows a basic-function, non-printing calculator. Seven of the eight tested modules have corresponding Performance Profiles.

What the current NCCER Core Level Test covers
The public module counts add up to 89. Construction Math is the largest published slice at 19 questions. What NCCER does not publish is the proprietary item bank, exact question difficulty, or a public subtopic-by-subtopic weighting. Our mock follows the public module allocation only.
| Module | Tested area | Questions | Performance Profile? |
|---|---|---|---|
| 00101 | Basic Safety | 13 | Yes |
| 00102 | Introduction to Construction Math | 19 | Yes |
| 00103 | Introduction to Hand Tools | 13 | Yes |
| 00104 | Introduction to Power Tools | 10 | Yes |
| 00105 | Introduction to Construction Drawings | 11 | Yes |
| 00107 | Basic Communication Skills | 9 | Yes |
| 00108 | Basic Employability Skills | 8 | No |
| 00109 | Introduction to Material Handling | 6 | Yes |

The Core curriculum has 10 modules; the Level Test currently uses eight
This distinction is easy to miss and worth getting right. NCCER's current Core catalog includes 00100 Build Your Future in Construction and 00106 Introduction to Basic Rigging as electives. Neither module appears in the March 2024 Core Level Test specification.
They can still be useful in a training program or required later in a craft pathway; they simply are not current Core Level Test domains. That is why this page keeps them under Curriculum Extras instead of quietly mixing them into the 89-question mock.

Study guide for the eight tested modules
00101 Basic Safety
Learn the reasoning behind safe work, not just a handful of numbers. Review construction fall hazards, hazard communication, PPE, tool and ladder inspection, housekeeping, electrical hazards, and excavation basics. When an explanation uses an exact federal threshold, this tool links it to the applicable OSHA construction standard.
00102 Construction Math
Math is the largest module in the published blueprint. Practice fractions, mixed numbers, decimals, measurement, unit conversions, perimeter, area, volume, percentages, proportions, the Pythagorean theorem, and practical layout math. On trade math, careful setup usually beats trying to look heroic in your head.
00103 Hand Tools
Be able to identify the right tool, inspect it, use it as designed, and recognize common misuse. The practice bank covers basic saws, hammers, wrenches, files, squares, levels, and layout tools.
00104 Power Tools
Review guards, power isolation before accessory changes or jam clearing, cord and plug inspection, GFCI protection, double-insulated tools, abrasive-wheel safety, pneumatic connections, and matching the tool to the task.
00105 Construction Drawings
Know what information belongs in title blocks and legends, how floor plans, elevations, and sections differ, what common line types communicate, and how drawing scales relate paper distance to real-world distance.
00107 Communication Skills
Jobsites are bad places for vague communication. Study active listening, repeat-back communication, clarification, factual incident reporting, work logs, shift handoffs, and handling barriers such as noise or incomplete instructions.
00108 Employability Skills
This module focuses on professional behavior: punctuality, accurate applications, interview preparation, teamwork, receiving feedback, appropriate phone use, continued learning, and recognizing when a task is outside your training.
00109 Material Handling
Practice lift planning, sound body positioning, knowing when to get help or use mechanical assistance, using hand trucks and similar equipment, stable storage, and controlling materials that can roll or shift.
Knowledge test vs. Performance Profiles vs. the Core credential
Passing the knowledge test is not the same as finishing every hands-on requirement. NCCER's Level Tests information distinguishes a knowledge-test certificate from a level credential, which also requires the applicable Performance Profiles.
For Core, the current Level Test specification marks Performance Profiles for seven of the eight tested modules. 00108 Basic Employability Skills is the exception.
If you are training through an Accredited Training Sponsor, ask your instructor or program coordinator which performance tasks apply to your pathway and how completions are recorded in the NCCER Registry.

How to use your practice score without fooling yourself
A 70 percent practice score is a sensible benchmark because it matches NCCER's published minimum passing score for the current Core Level Test. It is not a prediction. This is an independent question bank, and no third-party practice site should pretend it knows the proprietary items or exact difficulty you will receive.
- Find modules that stay weak across more than one session. One ugly question is noise; a recurring weak domain is useful information.
- Read the explanation, not just the correct letter. Memorizing A/B/C/D is spectacularly useless when the next variant changes the scenario.
- Retest missed concepts with a different variant before starting another full mock.
- Build margin above 70 percent. On an 89-question mock, 63 correct is at least 70 percent. If you are living right on that line, keep studying rather than treating 63 like a sacred number.
Where Core can lead next
Core is foundational. The next useful move is choosing the craft you want to build on top of it.
Credential reality check: An NCCER credential is not a state or local journeyman license. Licensing for trades such as electrical and plumbing is separate and varies by jurisdiction.
How this practice bank was built
The tested bank contains 89 editorial concept families with four independently written variants each, for 356 tested question variants. Eight additional concept families cover the two Curriculum Extras, bringing the complete bank to 388 original variants.
A session can serve only one variant from a concept family. That lets a full mock cover 89 distinct concepts instead of faking variety by asking the same question four times with a few nouns swapped around.
The bank does not copy, paraphrase, reconstruct, or claim access to proprietary NCCER exam items. It mirrors only the public module-level allocation. Safety explanations that use exact regulatory thresholds link to primary OSHA standards.
Frequently asked questions
Is this an official NCCER practice test?
No. Trade-Schools.net is independent from NCCER. The questions are original and use public curriculum scope, the published Level Test blueprint, common construction fundamentals, and primary safety sources.
How many questions are on the current NCCER Core Level Test?
The current Core Level Test Sixth Edition specification, updated March 2024, lists 89 questions across eight tested modules.
How long is the NCCER Core Level Test?
The current specification allows three hours and describes the test as closed book. A basic-function, non-printing calculator is allowed, and NCCER says a basic calculator is available in the online testing platform.
What score do you need to pass?
NCCER lists 70 as the minimum passing score for the current Core Level Test. On an 89-question practice mock, 63 correct is at least 70 percent.
Is Basic Rigging on the current Core Level Test?
No. The Core catalog lists Introduction to Basic Rigging (00106) as an elective, and the current Level Test specification does not include it among the eight tested modules. It can still matter in craft-specific training, so this tool keeps it in a separate Curriculum Extras section.
What happens if you do not pass the Core Level Test?
NCCER's Core Level Test guidance says a score below 70 requires repeating the full Level Test, not just the sections you missed. Ask your training sponsor about current scheduling, remediation, and pricing policies.
Does passing the knowledge test give you the full Core credential?
Not by itself. NCCER distinguishes the knowledge-test certificate from the level credential, which also requires the applicable hands-on Performance Profiles.
