The PMI-SP tests scheduling judgment across five weighted domains, from schedule strategy through closeout. Confirm your eligibility route, learn the domain weights, and build fluency in networks, float, baselines, and status updates by working small scheduling decisions through to a defensible answer.
What the PMI-SP credential covers
The PMI Scheduling Professional (PMI-SP)® is PMI's specialized credential for project schedulers, and its exam content is fixed by PMI's official Exam Content Outline.
PMI-SP recognizes specialist scheduling knowledge. Use its own Exam Content Outline to check preparation, even if you already hold a general project management credential.
The currently linked ECO has a 2012 copyright, and its five domain weights match PMI’s current certification page. Use the current link when preparing; the copyright alone does not establish that the outline has been replaced.

Eligibility routes before you apply
You qualify through one of three sets of requirements, each combining a degree, a period of scheduling experience within the last five years, and scheduling education hours.
PMI lists three eligibility sets for the PMI-SP. Check which one fits your background before you invest study time, and document your scheduling role carefully: PMI's application guidance says to describe your role and responsibilities on each project, not the project itself.
PMI accepts training in Microsoft Project and other scheduling tools toward scheduling education. Check the qualifying hours for your eligibility path; tool training does not replace the experience requirement.
- Set A: secondary degree, 40 months of project scheduling experience within the last 5 years, and 40 hours of project scheduling education
- Set B: four-year degree, 24 months of project scheduling experience within the last 5 years, and 30 hours of project scheduling education
- Set C: bachelor's or postgraduate degree from a GAC-accredited program, at least 12 months of professional project scheduling within the last 5 consecutive years, and 30 contact hours of scheduling education
- If selected for an eligibility audit, be ready to provide a copy of your degree, verification of experience signed by your supervisor, and certification or proof of project management experience
Exam format and appointment checks
The exam is 170 multiple-choice questions in 210 minutes: 150 scored plus 20 unscored pretest questions. It is taken at a Pearson VUE testing center, and you may attempt it up to three times within one year.
The 20 pretest questions are dispersed across the domains and do not count toward your score; PMI uses them to trial items before adding them to the question bank. The exam is offered in English.
Three practical facts complete the picture. You schedule the exam at a Pearson VUE testing center after your application is accepted and you pay the exam fee. You may attempt the exam up to three times in one year if you do not pass. After you pass, maintaining the credential means earning 30 professional development units (PDUs) in each three-year cycle.
A few booking details are not established by the sources behind this guide: the current exam fee, the passing score, the waiting rule between retakes, and whether online proctored delivery is available. Check PMI's certification page and your confirmation materials for those, since they can change independently of the content outline.

The five domains as study priorities
Monitoring and controlling (35%) and planning and development (31%) carry the most questions, so build your depth there, but every domain contributes.
The outline divides the scheduler's role into five domains. The percentages below are the proportions of exam items drawn from each domain, not a study-time quota, but they tell you where depth pays off most.
Alongside the domains, the outline lists cross-cutting knowledge and skills that appear across all of them: communication techniques, negotiation and facilitation, scheduling terminology, estimation techniques, scheduling methods and techniques, earned value management, Gantt charts, and quantitative schedule analysis such as float analysis and the schedule performance index. Treat these as connective tissue rather than a separate chapter.
| Domain | Weight | What it covers |
|---|---|---|
| Schedule Strategy | 14% | Schedule approach, configuration management, policies, tool and parameter selection, integration with project management plans |
| Schedule Planning and Development | 31% | WBS/OBS/RBS, activities and milestones, duration estimates, dependencies and constraints, critical and near-critical paths, resources, schedule risk analysis, approved baseline and Performance Measurement Baseline |
| Schedule Monitoring and Controlling | 35% | Activity and resource status collection, schedule analysis and audit, what-if alternatives, incorporating approved mitigation, formal baseline changes |
| Schedule Closeout | 6% | Contractual acceptance, lessons learned, final reports including EVM and variance analysis, archiving schedule files |
| Stakeholder Communications Management | 14% | Stakeholder relationships, schedule visibility, targeted status updates, raising delivery-impacting issues |

Choosing preparation material for this exam specifically
Start from the official Exam Content Outline and the two scheduling references it names, and map whatever else you study back to the five domains.
PMI recommends using current scheduling references alongside the ECO. Its preparation page lists the Practice Standard for Scheduling, third edition, and the PMBOK Guide.
Map each resource to the SP tasks. Work on baseline development, network analysis, resource constraints, schedule risk, updates and communication. The presence of a resource in a study plan does not establish complete coverage.

Understand the two float calculations
In the simple finish-to-start network below, total float compares an activity’s late and early dates; free float measures the gap before its earliest-starting successor.
Use total float = late finish − early finish, or late start − early start. For this network, free float = earliest successor early start − the activity’s early finish. The PMI scheduling standard explains these calculations.
Fix calendars, relationships, lags, constraints and resource assumptions before applying formulas. The worked example uses a single elapsed-day calendar, zero lags and enough resources for parallel activities.

Trace the network by hand before trusting any tool
A forward pass establishes early dates. A backward pass from the selected finish establishes late dates; compare them to calculate float.
This original exercise uses five activities and an explicit elapsed-time convention.
Worked example
Start at elapsed day 0. Use finish-to-start links, fixed durations, one calendar, no lags or date constraints, and enough resources for parallel work. A (5 days) precedes B (3 days) and C (8 days). D (4 days) waits for both B and C; E (2 days) follows D and ends the project. Use the calculated earliest project finish for the backward pass. Find early and late dates, B’s total/free float and the controlling path. Then compare a one-day delay to C with a one-day delay to B, leaving everything else unchanged.
Show answer
Early intervals: A 0–5, B 5–8, C 5–13, D 13–17, E 17–19. Late intervals: A 0–5, B 10–13, C 5–13, D 13–17, E 17–19. A–C–D–E controls the 19-day finish. B has 5 days total float and 5 days free float. A one-day C delay moves finish to day 20; a one-day B delay leaves finish at day 19.
D starts at max(8,13) = 13 and E finishes at 19. Backward from 19, E starts at 17, D at 13 and C at 5. B may finish at 13, so its late start is 10. B’s total float is 13 − 8 = 5; its free float is D’s early start 13 − B’s early finish 8 = 5. A must finish by the earlier of B’s and C’s late starts, min(10,5) = 5. Under these fixed assumptions, a C delay affects the controlling path; a one-day B delay fits within B’s available float.

Worked exercise: check every path before buying time
Shortening today’s controlling path can make another path control completion. Recalculate the entire network.
The scheduling standard distinguishes crashing, which adds resources to shorten suitable activities, from fast tracking, which changes overlap and can add rework risk. Neither guarantees a particular project saving without a complete model.
This fictional calculation allows only the stated duration reductions at the stated linear costs; all quality, safety, resource and other requirements are met. It is not a field work instruction.
Worked example
A project has two independent finish-to-start paths from a common start to a common finish: A (30 weeks)→F (10 weeks), and B (29 weeks)→G (8 weeks). Both paths must finish. There are no other activities, constraints, lags or resource interactions. A and B cannot change. F can be shortened by up to 4 weeks at $4,000 per week; G by up to 3 weeks at $2,000 per week. (a) What happens if only F is shortened by 4 weeks? (b) What is the minimum stated cost to finish in 36 weeks?
Show answer
(a) The paths become 36 and 37 weeks, so the project finishes in 37 weeks. (b) Shorten F by 4 weeks and G by 1 week: both paths become 36 weeks, at a total cost of $18,000.
Initially the paths take 40 and 37 weeks. F alone cannot bring both paths to 36. The first path needs at least 4 weeks removed and the second at least 1 week; only F and G can supply those reductions. Minimum cost is 4 × $4,000 + 1 × $2,000 = $18,000. After reducing F by 3 weeks both paths tie at 37 weeks, so the final week requires shortening both. G’s initial float does not make it permanently irrelevant.

Update forecasts from evidence
Record actual progress and assess remaining work before recalculating the forecast. A percent-complete figure alone does not fix the remaining duration.
Check how progress was measured, the work remaining, resources, dependencies and any changed conditions. Assuming the future rate equals either the original plan or the recent rate needs justification.
For a self-contained arithmetic example, suppose 50 of 100 identical units took 15 working days and the remaining units will be produced at exactly the same constant rate with unchanged resources and no interruptions. Then the remaining 50 units require 15 working days. Without that constant-rate premise, the observation alone does not establish the forecast.
Keep forecast updates and baseline approvals distinct
Report the current forecast against the approved baseline, and document baseline changes through the formal change-control process.
The monitoring tasks cover status collection, schedule analysis, approved changes and records supporting later review. A slipping forecast does not by itself approve a new baseline.
Retain the relevant baseline and change history. At closeout, obtain acceptance, evaluate performance, record lessons, distribute final reports and archive the schedule files as required by the project’s procedures.
Your preparation checklist
Check eligibility, cover every domain and practise calculations with their assumptions visible.
- Document your scheduling experience and qualifying education.
- Map resources to all five SP domains and cross-cutting skills.
- Calculate small networks by hand and test what changes when a path is shortened or delayed.
- Review resource constraints, risk analysis and controlled baseline changes.
- Practise communicating forecast changes and closeout results.
- Confirm your appointment requirements, including any break or delivery rules, directly with PMI.
