OpenExamPrep
NCCER Telecommunications is a competency-based craft curriculum whose written assessments are multiple-choice knowledge tests, one per module, plus comprehensive level tests that combine all module items. Candidates earn a Knowledge Verified credential when they meet the passing percentage (typically 70 percent or higher) and a separate Performance Verified credential for hands-on cabling tasks. There is no single national fee or fixed exam time; module and level tests are delivered through NCCER Accredited Sponsors using the NCCER Testing System. Content covers telecom safety and tools, copper and fiber cabling, structured cabling standards (TIA-568/569/606/607), testing and certification, coax, wireless and NEC codes (Articles 800 and 770). This 100-question bank provides original multiple-choice practice across those areas.

About the NCCER Telecom Exam
NCCER Telecommunications is a competency-based craft curriculum that trains technicians to install, terminate, test and certify copper, fiber-optic and coaxial cabling in commercial and residential structured cabling systems. The curriculum is organized into modules across one or more levels, each ending in a written multiple-choice knowledge test, with separate hands-on performance verifications for tasks such as terminations, splicing and testing. Content spans telecom safety and tools, copper twisted-pair fundamentals and terminations, structured cabling standards (TIA-568, 569, 606 and 607), fiber-optic cabling and splicing, testing and certification, coax and broadband, wireless and DAS basics, and applicable codes including NEC Articles 800 and 770. Passing a module test earns a Knowledge Verified credential, and completing all modules in a level earns an NCCER level completion credential. This 100-question bank gives original multiple-choice practice modeled on those module knowledge areas.
Assessment
Competency-based craft made up of multiple modules across curriculum levels. Each module ends in a written multiple-choice knowledge test, and separate hands-on performance verifications cover cabling and termination tasks. Level tests combine items from every module in a level.
Time Limit
Set per module and per level test in the NCCER Testing System rather than as one fixed national time; comprehensive level tests are longer than individual module tests.
Passing Score
Knowledge Verified is awarded when the test passing percentage is met; NCCER's typical end-of-module and level standard is 70 percent or higher, with the exact cut score set in the testing system.
Exam Fee
NCCER does not publish a single national fee. Module knowledge tests, level tests and performance verifications are delivered through NCCER Accredited Training and Assessment Sponsors, who set local registration and testing costs. (NCCER Accredited Training Sponsors and Assessment Centers using the NCCER Testing System, under the National Center for Construction Education and Research.)
NCCER Telecom Exam Content Outline
Telecommunications Safety, Math and Tools
Electrical safety and lockout/tagout, ladders, lifts and aerial work, fall protection while working aloft, confined-space awareness, PPE, telecom math, and the hand and power tools used to pull, terminate and test cable.
Copper Cabling Fundamentals and Terminations
Twisted-pair UTP and STP categories (Cat 5e, Cat 6, Cat 6A), balanced pairs and color codes, T568A and T568B pin/pair assignments, RJ-45 plug and jack terminations, patch panels, 110 and 66 punch-down blocks, and impairments such as crosstalk (NEXT/FEXT), attenuation and untwist limits.
Structured Cabling Systems and Standards
TIA-568 cabling, 569 pathways and spaces, 606 administration, and 607 grounding and bonding; horizontal and backbone subsystems; work area, telecommunications room, equipment room and entrance facility; the 90 m horizontal channel rule; and grounding/bonding of telecommunications systems.
Fiber-Optic Cabling
Single-mode versus multimode fiber and core sizes, OM/OS designations, connectors (SC, LC, ST and MPO), fusion and mechanical splicing, end-face polishing (PC/UPC/APC), connector loss, loss budgets, and OTDR and power-meter testing.
Testing, Certification, Coax and Wireless
Cable certifiers versus qualifiers and verifiers, continuity and wiremap, length, NEXT, return loss and insertion loss, fiber loss testing with light source and power meter, coaxial and broadband cabling, and wireless and distributed antenna system (DAS) basics.
Codes and Administration
NEC Article 800 communications circuits and Article 770 optical fiber, cable listings and the plenum/riser/general-purpose hierarchy (CMP, CMR, CM/CMG), and TIA-606 labeling, records and administration of the cabling system.

Frequently Asked Questions
Is the NCCER Telecommunications exam one test or many?
It is many. Telecommunications is a competency-based craft made up of modules across curriculum levels. Each module has its own written multiple-choice knowledge test, and level tests combine the items from all modules in a level into one comprehensive test.
What is the difference between Knowledge Verified and Performance Verified?
Knowledge Verified means you passed the written multiple-choice test for a module or level. Performance Verified means a qualified NCCER evaluator confirmed you can perform the hands-on tasks, such as terminations, splices and testing. Both are tracked in the NCCER registry.
What passing score do NCCER module and level tests use?
Knowledge tests are scored as Knowledge Verified when the passing percentage is met. NCCER's typical standard for end-of-module and level tests is 70 percent or higher, with the exact cut score configured in the NCCER Testing System.
Which standards and codes does the Telecommunications curriculum cover?
It covers the TIA-568, 569, 606 and 607 structured cabling standards along with NEC Article 800 (communications circuits) and Article 770 (optical fiber), plus copper and fiber installation, termination, testing and certification practices.
How much does it cost to take the NCCER Telecommunications tests?
NCCER does not publish a single national fee. Module knowledge tests, level tests and performance verifications are delivered through NCCER Accredited Training and Assessment Sponsors, who set their own local registration and testing costs.
Are these official NCCER test questions?
No. These are original OpenExamPrep practice questions modeled on the NCCER Telecommunications knowledge areas. Official NCCER module and level tests are delivered separately through Accredited Sponsors using the NCCER Testing System.
