PERT

No single body owns it. PERT is a scheduling technique, and exams on it are administered by training providers, universities, and professional associations. Check the specific organization you are registering with for its content outline; this page is independent study material and is not affiliated with any issuer.

It varies by provider, so there is no universal answer. The administering organization publishes the current format, item count, and time limit on its own site - confirm there before you book. Plan on a mix of multiple-choice calculation items and short interpretation questions.

The conceptual content is modest; the difficulty is arithmetic under time pressure. Candidates who lose marks usually mis-square variances, sum standard deviations instead of variances along a path, or forget that only the critical path drives project variance. Fluent, error-free hand calculation is what separates a pass from a near miss.

Most providers supply one, and you should confirm whether yours does. Either way, practise reading it quickly and in both directions: turning a z-score into a probability, and reading the z-value you need for a target confidence level. Knowing the common z-values by heart saves time.

Combining path standard deviations by adding them. Variances add along a path and standard deviations are the square root of that sum. The second most common error is treating a near-critical path as irrelevant when its variance is large enough to overtake the critical path's risk.

Network modelling first, because everything else depends on a correct diagram. Then three-point estimating, then critical path and float, then probability. Doing probability before you can build a clean network means you will be applying formulas to the wrong path.

Retake rules, waiting periods, and any fees are set by the individual provider. There is no industry-wide policy. Look for the retake section in your provider's candidate handbook, and check whether it offers a scoring breakdown that tells you which domain to work on.

There is no standard passing score for PERT-based exams. Each provider sets its own cut score and may or may not publish it. Consult the administering organization's site for the current figure rather than relying on numbers quoted in forums or study groups.

Provider-dependent. Where calculators are permitted, they are usually basic (no programmable memory). Practise with whatever you will actually have, and get comfortable squaring and square-rooting decimals by hand so you are not derailed if devices are barred.

Not automatically. Several project management bodies award professional development units for training, but PERT study alone typically does not satisfy experience requirements. Check the specific credential's rules; treat PERT mastery as a skill, not as transferable credit.
