Companies that use the CCAT, and what each one asks for
Four employers confirm on their own pages that they use the CCAT: Crossover, Hack Reactor, BloomTech and Gauntlet AI. Their rules differ. BloomTech asks for 23 correct and allows retakes, Gauntlet AI asks for 40 with one attempt per cohort, Hack Reactor makes you wait three months, and Crossover allows one attempt every six months.
Confirmed employers and their rules
Each row comes from the employer's own page, checked on 6 Nov 2026.
| Employer | Score bar | Retake rule | Source |
|---|---|---|---|
| Crossover | Not published | One attempt per email address in a six-month period; a new role needs a new CCAT (since 21 Jan 2019) | Crossover CCAT FAQs |
| Hack Reactor | "Within the suggested range provided by Criteria" | Below the range: wait three months before taking it again | Hack Reactor |
| BloomTech | 23 or more correct | "You can re-take it!" (no waiting period stated) | BloomTech |
| Gauntlet AI | 40 or more, "around the 98th percentile" | "You only get one shot per cohort" | Gauntlet AI |
What each one tells you
- Crossover lists the CCAT as one of the tests required when you apply, and says it can't share CCAT scores or give feedback (Crossover).
- Hack Reactor, the coding bootcamp, requires the CCAT of all applicants (Hack Reactor).
- BloomTech, formerly Lambda School, requires 23 correct to move forward (BloomTech).
- Gauntlet AI requires 40 for admission. Its admissions CCAT is unproctored, but a proctored version follows later in the program and the results are compared (Gauntlet AI).
Note the range. 23 is just under the norm-group median of 24; 40 is near the top 1% on our estimate (Criteria InfoBrief). The same raw score can be a clear pass at one employer and far short at another. See what yours means on the CCAT score page.
Reported elsewhere, not confirmed
Some prep sites publish long lists of companies said to use the CCAT, including large investment groups, insurers and restaurant chains. None of the lists we read links to the employer's own page, so we don't repeat the names. If a company invites you to a Criteria test, the invitation is the confirmation that counts.
How to check your own employer
- Search the employer's careers or admissions pages for "CCAT" or "Criteria". Bootcamps often publish their bar.
- Read your invitation email. It names the test and gives the deadline for your link.
- Ask the recruiter what score range they use and whether retakes are allowed. Criteria's support team can't answer that for them.
The rules that apply everywhere
- Criteria publishes no universal retake rule. Retakes are the employer's decision (Criteria help).
- Results don't transfer between companies, so you test again for each employer (candidate FAQs).
- Your link has a deadline, and Criteria support can't extend it for the employer (candidate FAQs).
If an employer gives you one attempt, your first try is the one that counts. Practice with a full CCAT practice test under the real 15-minute clock first.
