What employers actually ask for
Credentials named in the 46 postings we read, ranked by how many mentioned each one.
None. Across 46 postings, no certification or licence was named often enough to call it a requirement. For this role in this market, employers are hiring on demonstrated work rather than credentials — which means money spent on a certificate here is unlikely to be what gets you the interview.
What the official taxonomy says
O*NET surveys people already doing this job. That describes who got hired over a long window, not what employers are asking for now — where it disagrees with the counts above, the counts are the more current answer.
- High school diploma or equivalent
- Bachelor’s degree
- Less than high school diploma
Job Zone Three: Medium Preparation Needed. Most occupations in this zone require training in vocational schools, related on-the-job experience, or an associate's degree.
