Postal Exam 960 (Custodian): what the posting says, what's unknown, and how to prepare
Exam 960 is the custodial exam named on 2026 postings for Laborer Custodial and Custodian jobs. Much of it is not publicly specified: the official exams page still lists the older custodial Exam 916, and there is no published information package for 960. What we know comes from the postings themselves and from job standards published by the union in August and September 2026.
Two rules matter before the exam: outside hiring for these jobs is restricted to veterans' preference eligibles while they're available (federal law and postal policy), and postings refer "a set number of the highest-ranked eligible candidates", so your result is ranked, not just pass/fail.
PostalPath is an independent company and is not affiliated with, endorsed by, or connected to the United States Postal Service. Applying for USPS jobs is free at usps.com. Applying and taking the assessment are free; the posting or your invitation names the exact assessment, and PostalPath’s guidance is a starting point, not an official determination.
Who takes Exam 960
- Laborer Custodial
- Custodian
- Group Leader Custodial
How the assessment starts
- Custodial jobs are posted on the older eCareer career search; check the posting's eligibility paragraph (veterans' preference restriction) before you apply.
- Your invitation email tells you whether you test online or at a test center, and your deadline. Start as soon as it arrives: a missed deadline is an ineligible result for that posting.
- If the exam is at a test center, you can cancel or reschedule up to 24 hours ahead; a no-show is an incomplete result and no retest for that vacancy.
The rules at a glance
| Sections (from the posting) | Technical: Hand Tools, Safety and PPE, Cleaning. Non-technical: Behavioral Characteristics, Following Instructions |
|---|---|
| Question count, time limit, location | Not published; your invitation is the rule |
| Scoring and passing | Not published for Exam 960. On postal exams generally, a result is a score (70 passes on most scored exams, including the older Exam 916) or simply eligible/ineligible |
| Ranking | Applicants are ranked; postings refer a set number of the highest-ranked eligible candidates |
| If you don't pass | No retest for the same posting. You can retest on or after the Retest Eligibility Date on your notice by applying to another posting; the waiting period for 960 isn't published. A retest result replaces your old one |
| Your result | Reused for other postings that require the same exam until the expiration date on your notice (policy minimum: two years) |
| Exam 916 scores | Whether an older Exam 916 score counts for a posting that requires 960 hasn't been announced |

The sections on Exam 960
| Section | What you do | Scored? |
|---|---|---|
| Hand Tools | Identifying and using common hand tools | Not published |
| Safety and PPE | Safe practices and personal protective equipment (gloves, goggles, masks, safety shoes, hearing protection) | Not published |
| Cleaning | Cleaning methods, chemicals and equipment | Not published |
| Behavioral Characteristics | Work-style questions (format not published) | Not published |
| Following Instructions | Reading and carrying out instructions accurately | Not published |
Three of these section names resemble the older Exam 916 (safety, cleaning, following instructions); 960 adds Hand Tools and Behavioral Characteristics and doesn't list 916's vocabulary and reading part. Beyond the names, how similar the two exams are isn't known. PostalPath's Exam 960 practice covers the five named sections with original questions; its lengths and timings are our own design, not the official format.
How your score is used
- Scoring isn't published. Assume every section counts and aim to do well on all five, because applicants are ranked.
- Veterans' preference points, where they apply, are added to a passing score.
- A current result is reused automatically for other postings that require the same exam.

Tips that actually matter
- Confirm your eligibility first: most outside hiring for custodial jobs is restricted to veterans' preference eligibles, and postings say how they handle it.
- Learn the names and uses of common hand tools, and the PPE that goes with each cleaning task.
- Practice reading a short set of instructions and carrying them out exactly, in order.
- Answer the behavioral questions honestly; the format isn't published, and honest answers stay consistent on their own.
- Keep your invitation: it's the only document that states your test format, location and deadline.
