Examination and retest policy

One attempt per examination is included. The main examination contains 100 questions and requires 80% (80/100); the weld examination requires 90% (54/60).

After an unsuccessful attempt, a minimum of 14 calendar days must pass before a retest. Each retest costs $150 per failed examination and requires verified payment, completed review of assigned subjects, and ATC authorization. Payment alone does not unlock an examination.

One paid retest is available after ATC approval. After a second unsuccessful attempt, additional training and documented instructor review are required before any further authorization. ATC may document a fee waiver. Verified technical interruptions are reviewed separately from academic failures.

Each authorization permits exactly one attempt and expires 30 calendar days after approval. If the original training window has ended, authorization provides access only to that examination; online modules and operator courses are not extended. Certificates remain available through My Certificates.

Feedback may identify subjects needing review. Exam questions and answer keys are protected. To request review, contact brian@atc578.com.
