ASE recertification and the Renewal App, explained

Quick answer

How does ASE recertification and the Renewal App work?

Every ASE certification is valid for 5 years. Automobile Series (A1-A9) holders can renew through the ASE Renewal App: 1 question per certification every 30 days, 8 correct answers extends that certification 1 year, $52/year covers every A1-A9 cert held. Every other series (B, C1, F1, G1, H, L2-L4, P, S, T) has no Renewal App option yet and renews only by retaking a recertification test, which usually runs about half the length of the original exam.

The short version

Every ASE (National Institute for Automotive Service Excellence) certification is good for 5 years from the date you earn it. Before that 5-year clock runs out, you have to do one of two things to keep it current: retake a shortened recertification test, or, if you hold an Automobile Series certification, work through the ASE Renewal App instead. Nothing lapses without warning, and a lapsed certification is not a dead end: ASE lets you retest even after the expiration date has already passed.

This page is not affiliated with or endorsed by ASE. It exists to lay out the mechanics of both renewal paths in one place, sourced directly from ASE’s own published pages, so you can decide which one fits your situation before your deadline is close enough to be stressful.

Path 1: the ASE Renewal App, and who can actually use it

A common assumption is that the Renewal App works for any ASE certification. It does not, at least not yet. ASE states plainly that the app currently covers only the Automobile Series, A1 through A9. If your certifications are all in the Automobile Series, this is your fastest and cheapest renewal path. If you hold a Collision Repair (B-series), Truck (T-series), School Bus (S-series), Transit Bus (H-series), Advanced Specialist (L2 through L4), Parts Specialist (P1, P2), Service Consultant (C1), Alternate Fuels (F1), or Maintenance and Light Repair (G1) certification, the Renewal App is not an option for that certification today, period. ASE’s own copy notes that additional certifications “may be added in the future,” so it is worth rechecking as your renewal date approaches, but treat it as not-yet-available rather than assume it will apply to you.

For the certifications it does cover, here is how it actually runs:

Path 2: the recertification retest, available to every series

Every other certification, and every Automobile Series holder who would rather just retest instead of subscribing to the app, renews the traditional way: retake a recertification test before or after the 5-year window closes. ASE’s own published guidance says these recertification tests usually run about half the number of questions of the original certification exam. ASE does not publish an absolute question count or time limit for the shortened retest on its own pages, so treat “about half” as the honest, sourced figure rather than an exact number until a specific test’s shortened length is separately confirmed. The retest fee is also not published on ASE’s site; ASE routes fee questions to its own customer care line rather than listing a page price, so budget for a call or a check at registration rather than a number quoted here.

The one genuinely reassuring fact: there is no hard cutoff. ASE explicitly allows you to take the recertification test even after your credentials have already expired. A lapsed certification is inconvenient, not permanent.
