NCCER (the National Center for Construction Education and Research) writes the Core curriculum that every NCCER craft starts with, and its tests. Training programs test Core either one module at a time or with the single Core Level Test, which covers the eight required modules. These pages follow the 6th edition, the edition in force (checked November 2026).
- What it is
- NCCER Core: Introduction to Basic Construction Skills is the entry curriculum for every NCCER craft, used in high school career and technical programs, pre-apprenticeship and company training. The current edition is the 6th, revised in 2021
- Modules
- Ten: Build Your Future in Construction (00100, elective), Basic Safety (00101), Construction Math (00102), Hand Tools (00103), Power Tools (00104), Construction Drawings (00105), Basic Rigging (00106, elective), Communication Skills (00107), Employability Skills (00108) and Materials Handling (00109). The eight required modules total 75 instruction hours
- How you are tested
- Either a written test for each module or the single Core Level Test that combines the eight required modules. Tests run online in the NCCER Testing System, given by an NCCER-accredited training program in person or with NCCER remote proctoring
- Core Level Test
- 89 items in a three-hour, closed-book test: Basic Safety 13, Construction Math 19, Hand Tools 13, Power Tools 10, Construction Drawings 11, Communication Skills 9, Employability Skills 8, Materials Handling 6
- Passing score
- A minimum score of 70 on the Core Level Test. Below 70, the whole test is taken again; there are no section retakes
- Calculator
- A basic-function, non-printing calculator is allowed, and the NCCER Testing System has one built in. No papers, books or notes
- Hands-on part
- Performance profiles: tasks you complete for your instructor in every tested module except Employability Skills. The credential needs the test and the profiles
- Module tests
- NCCER does not publish module-test lengths or time limits on its public pages; they are set in its accreditation standards for training programs
- Cost
- Billed to the training program. NCCER’s 2021 launch notice set the Core Level Test at $27 per attempt, retests included. Students usually do not pay NCCER directly
- Credential

Where the test fits in earning the NCCER Core credential
- Enroll in an NCCER-accredited training program: a high school career and technical program, a pre-apprenticeship, a craft training center or an employer program.
- Work through the Core modules with your instructor (75 instruction hours for the eight required modules in the 6th edition).
- Take the module tests or the Core Level Test online in the NCCER Testing System, in person or with NCCER remote proctoring.
- Pass with a score of 70 or more and complete the hands-on performance profiles your instructor signs off.
- View and print your credential in your NCCER account, then move on to a craft curriculum such as carpentry, electrical, HVAC, plumbing or welding.
How to use this NCCER Core test prep
- Take the free mixed drill to see where you stand across the modules.
- Drill construction math first: it is 19 of the 89 items, more than any other module, and a basic calculator is allowed.
- Drill basic safety and hand tools next (13 items each), then construction drawings (11) and power tools (10).
- Clear communication skills, employability skills and materials handling (23 items together); these reward careful reading.
- Take the full 89-question practice test under the three-hour clock, then drill your two lowest modules and take it again. Each new sitting draws questions you have not seen first.
- If your program teaches Basic Rigging, use its guide and drill before the module test; it is not on the Core Level Test.
