FAQ

CAST — Common Questions

What is the CAST test?

CAST (Construction and Skilled Trades) is the EEI selection test used by utilities and energy companies for trades roles — line worker, substation, meter, gas, and similar positions. It has four parts: graphic arithmetic, mechanical concepts, reading comprehension, and mathematical usage.

What score do I need to pass the CAST?

Each employer sets its own cutoff, reported on a 1-10 index. Most utilities look for a minimum index around 4-6 for trades positions. Higher scores improve your ranking against other applicants.

How should I prepare for the CAST?

Practice under timed conditions. The math is not advanced, but the pacing is aggressive — graphic arithmetic gives you about 30 problems in 30 minutes reading values off drawings. Our book includes 3 full-length timed tests that mirror the real pacing.

What is included with the CertPath CAST book?
