The Certified Perl Programmer (CPRP) is an intermediate, vendor-neutral certification for people who write Perl. It validates that you understand Perl fundamentals and syntax, can work with scalars, arrays and hashes, can control program flow and write subroutines, can use regular expressions to process text, can work with references, modules and the standard library, and can handle files, errors and best practices. The exam is computer adaptive and performance-based, and the credential is kept current through continuing education.
| Level | Intermediate. It assumes some hands-on Perl or programming experience and validates programming in Perl end to end. |
|---|---|
| Delivery model | Computer adaptive, three stages. Your score on each stage selects the difficulty of the next, so no two candidates sit the same paper. |
| Format | 80 questions. A performance-based exam that includes performance-based questions and multiple-choice questions. Concepts transfer across every Perl project and employer. |
| Time | 120 minutes for the whole exam, timed. Autosaves every answer. |
| Scoring | You need a score of 700 out of 900 to pass. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly. Harder questions carry more weight, so a score means the same thing on any route. Multiple-response items and PBQs are all or nothing. |
| Retakes | No waiting period after a failed first attempt. Every attempt is paid for at the exam price. See the CertLabz Certification Retake Policy. |
| Voucher validity | 12 months from purchase, for one sitting. |
| Certification validity | 3 years. Renew with 50 CEUs per cycle and the $35 annual CE fee, or pass the current exam. Renewal details. |
| Language | English. |
| Credential | PDF certificate with QR code, public verification page, LinkedIn-ready credential ID. Issuer: CertLabz Certification Board. |
| Free resources | The exam objectives PDF and the ten sample questions PDF. |

A signed, verifiable:
The CPRP is a performance-based exam: it includes performance-based questions alongside multiple-choice questions. Instead of only picking A, B, C or D, you match language features to their use, order the steps of a task, fix a broken piece of code, and choose the right approach. It is computer adaptive, is proctored and timed, needs no mandatory course, and tests programming in Perl rather than reciting one vendor's tooling.
The interpreter, variables, operators, statements, comments and packages.
Scalars, arrays, hashes, context, slices and built-in functions.
Conditionals, loops, subroutines, arguments, return values and scope.
Patterns, matching, substitution, references, modules, files and error handling.
Perl still runs a large share of the text processing, automation and glue code the software world depends on, and skilled Perl programmers are in demand across every industry. Every route is shown here at once, so nothing is hidden behind a control you have to find.

Every form is drawn from a bank of more than 90 items to these exact weights, whichever adaptive route you take. Filter by the area you want to study.
The exam runs in three stages. Your score on each stage selects the difficulty of the next, so a strong candidate is stretched and a struggling one is measured fairly rather than swamped. No two candidates sit the same paper. Harder questions carry more weight, so a scaled score means the same thing whichever route you took.
Each exam can have up to 5 to 12 performance-based questions, drawn fresh on every attempt, alongside the multiple-choice questions. A PBQ is a task rather than a list: you match language features to their use, order the steps of a task, fix a broken piece of code, or choose the right approach. They are scored all or nothing, so partial guesses do not pass.
The CPRP is vendor neutral and describes Perl generically, naming tools only as examples. It tests the Perl judgement that transfers across projects and employers.
Yes. Where a capability such as a module or a pragma is involved, it is described by what it does, not tied to one vendor.
700 out of 900. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly.
There is no waiting period between a failed first attempt and a second attempt. Buy another voucher and sit the exam again when you are ready, and it will draw a fresh adaptive form from the bank. See the CertLabz Certification Retake Policy.
Yes, after three years. Keep it current by logging 50 CEUs during the cycle and paying the $35 annual CE fee before expiry, or by passing the current exam again.
The exam objectives PDF and the ten sample questions PDF. The CPRP Official Study Guide is a $50 ebook, included in two of the bundles. Hands-on practice comes with the All Access plan, included in the Complete bundle.
A laptop or desktop with a webcam and microphone, Chrome, Edge or Firefox, a stable connection, and a quiet private room for two hours. Phones and tablets are not supported.
CPRP is a continuing-education certification, like the CE credentials from CompTIA and ISC2. It is valid for three years from the day you pass. To keep it, log 50 continuing-education units during the cycle and pay the $35 annual CE fee before your expiry date. Or pass the current version of the exam again. Earning a higher-level CertLabz certification renews it too, the way CompTIA certifications stack.
CEUs are logged from your CertLabz dashboard with supporting evidence. A certification that lapses can be reinstated only by passing the current exam.
