Utility route

Which test each utility gives

CAST is the best-known utility test, but it isn’t the only one. Several big utilities now use their own online assessments with no practice test at all. Only utilities whose own pages we could read are listed as confirmed.

Checked against official pages October 24, 2026. Non-official sources are labeled.

Ameren (MO/IL)
CAST confirmed
EEI CAST-R (or GPPB)
Needs a “Recommended” result. Retake after 30 days if invited, max 3 per calendar year. Accepts another company’s “Recommended” if it meets Ameren’s threshold. Class A permit before day one, license within six months.
Southern California Edison
CAST confirmed
EEI CAST + physicals
CAST (Test #5108), Groundman and Lineman Physical Performance tests, and a 35-foot pole climb test.
Seattle City Light
CAST confirmed
CAST + physical + working test + panel
CAST aptitude assessment, then three physical tests (chin-ups, upright rows, grip strength), a hands-on test and an oral panel.
Eversource / CT State lineworker program
Unconfirmed
EEI CAST + agility test + interview
CT State’s lineworker certificate program, run with Eversource, says “The CAST test is required for admittance to the program.” That is the training program’s entry rule; Eversource’s own apprentice hiring page doesn’t state it.
LG&E and KU
CAST confirmed
EEI CAST
CAST for transmission and distribution, substation and facilities jobs. No retake within 90 days.
Duke Energy
Own online assessment
VAL (Virtual Assessment for Lineworkers)
Virtual Assessment for Lineworkers: 65 minutes online, 72 hours to finish once invited, no retake for 90 days. Sections include mechanical knowledge, troubleshooting a visual, working with numbers and reading dials and gauges, plus behavioral parts. Duke says no practice test exists.
Dominion Energy
Own online assessment
Virtual Job Tryout
45 minutes online, including Line Worker: handle work challenges, check for errors, solve mechanical problems. Dominion says no practice test exists.

Online assessment with Lineworker listed as an example role; the link expires 72 hours after it’s sent. Journey-level distribution line workers take an additional assessment.
PG&E
Own online assessment
ALP hands-on assessment

TVA
Unconfirmed
ETA aptitude test (reported)
Reported to require the electrical training ALLIANCE aptitude test, which TVA’s page reportedly calls “formerly known as the AIR test.” We couldn’t open TVA’s page to confirm.
PECO / ComEd (Exelon)
Unconfirmed
CAST available
Exelon lists CAST among its available tests and hosts EEI practice, but doesn’t say which line jobs require it.

Not on the list?

Georgia Power, Xcel, Entergy, NextEra, DTE and CenterPoint have job postings that mention CAST, but we couldn’t read a live official page for any of them, so we don’t list them as confirmed. Electric co-ops generally don’t publish a written test: they hire from line schools, require a CDL and interview. Line contractors generally don’t either. Check the job posting itself; it usually names the test.
