- The exam is 75 questions in 90 minutes, and 80% is required to pass.
Why the CGM Has No Fixed Exam Calendar
If you searched for "CGM exam dates 2026" hoping to find a list of Saturday sittings at testing centers, here is the first thing to know: the Certified Grounds Manager credential, administered by the Professional Grounds Management Society (PGMS), does not work that way. The initial exam is delivered online with an approved proctor, and the timeline that matters is built around your enrollment rather than a shared national date.
That changes how you plan. Instead of circling a date and working backward, you work from the moment your application is approved and your testing window opens. Two clocks then run in sequence: a 30-day window to complete the initial exam, followed by a one-year deadline to submit your portfolio. This guide walks through both clocks, the eligibility steps that must happen first, and how to arrange your preparation around them.
How the Certified Grounds Manager Process Works
The CGM is a two-stage credential. The first stage is the application exam, a proctored online test. The second stage is the PGME portfolio, which is graded separately using a portfolio rubric and requires mentorship and evidence submission. Understanding that these are distinct deliverables with distinct deadlines is the key to scheduling well.
| Stage | What It Involves | Timing Constraint |
|---|---|---|
| Eligibility and application | Document your education and grounds/supervisory experience; confirm at least one year at your current facility | Must be approved before testing |
| Initial online exam | 75 questions, 90 minutes, multiple-choice and true/false, approved proctor | 30-day initial testing window |
| PGME portfolio | Mentorship plus evidence submission, graded on a separate rubric | Due within one year |
| Maintenance | 25 CEUs, at least 80% PGMS-approved | Every three years |
For a closer look at how the two stages differ in difficulty, see our breakdown in How Hard Is the CGM Exam? Complete Difficulty Guide 2026.
The 30-Day Initial Testing Window
The most important date-related fact about the Certified Grounds Manager exam is the 30-day initial testing window. Once that window is open, you have 30 days to take the proctored online exam. This is much tighter than the one-year portfolio horizon, and it is the part of the process where procrastination hurts most.
What the window means in practice
- Do your studying before the window opens. Thirty days is enough to schedule a proctor and sit the test, not to learn seven subject areas from scratch.
- Line up your proctor early. The exam requires an approved proctor, so confirm who qualifies and when they are available before your window begins.
- Test your technology. An online proctored exam depends on your connection and setup. The supplied references do not spell out equipment or home-testing rules, so verify them with PGMS ahead of time.
- Protect your calendar. Block a 90-minute session plus a buffer on more than one possible day within the window, in case something goes wrong on your first choice.
Eligibility Comes Before Any Scheduling
You cannot book anything until your eligibility is established, so the real start of your timeline is the application. PGMS sets experience and education requirements, and every pathway also requires at least one year at your current facility.
| Education Background | Grounds Experience | Supervisory Experience |
|---|---|---|
| Relevant four-year degree | Four years | Two years |
| Two-year degree | Six years | Three years |
| No qualifying degree | Eight years | Four years |
Gather employment records, supervisory documentation, and degree verification before you apply, because delays in paperwork push your whole timeline back. Our full rundown is in CGM Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees, Retests, and Budgeting Around Your Window
Fees are tied to PGMS membership status, and they affect when it makes sense to apply. Joining PGMS as part of your application is an option, and comparing the totals can help you decide.
| Applicant Type | Fee |
|---|---|
| PGMS member | $200 |
| Non-member | $300 |
| Join and apply together | $400 |
| Retest | $50 |
The $50 retest fee is modest, but the 30-day window means a retake has to fit inside your timeline, so build in margin rather than counting on a second attempt. For the complete financial picture, including renewal costs, read CGM Certification Cost 2026: Complete Pricing Breakdown.
What You Will Face on Test Day
Knowing the format helps you decide how ready you need to be before opening your window. The initial exam consists of 75 questions delivered in 90 minutes, a mix of multiple-choice and true/false items. You need 80% to pass. PGMS does not publish how the questions split between scored and unscored items.
That works out to a little over a minute per question, which is comfortable for recall-based items but unforgiving if you are slow on applied scenarios. For the exact threshold, see CGM Passing Score 2026: Exactly What You Need to Pass.
The One-Year Portfolio Deadline
After the exam comes the PGME portfolio, and this is where the Certified Grounds Manager differs sharply from a typical one-and-done certification. The portfolio is due within one year and requires mentorship and evidence submission. It is graded separately with a portfolio rubric, and PGMS does not publicly disclose a pass rate for it.
The portfolio is organized around nine PGME categories. These are portfolio categories, not exam domains, so do not mix them up with the seven subjects you study for the test. Because evidence gathering and mentorship take real time, many candidates start collecting material well before their exam window.
- Start the mentorship relationship early. A mentor's availability can become a bottleneck if you wait until after you pass the exam.
- Collect evidence as you work. Photos, plans, records, and project documentation are easier to gather in real time than to reconstruct later.
- Treat one year as a ceiling, not a target. Finishing early leaves room for revisions.
Mapping Seven Subjects Across Your Window
The PGMS handbook lists seven illustrative application-exam subjects. They are unweighted preparation headings, not a complete or weighted blueprint, and PGMS does not publish a largest-domain weight. That means you should prepare evenly rather than betting on one heavy area. The handbook's annotations date to 2022 and no dated current blueprint is available, so use the headings as a guide and confirm current expectations with PGMS. Our CGM Exam Domains 2026: Complete Guide to All 7 Content Areas covers each in depth.
Because the 30-day window is short, do your content review in the weeks before it opens. Here is one way to sequence the subjects, starting with the ones that tend to demand the most memorization and connecting related topics:
Soils and Turf Grasses
- Soil properties and how they drive turf and plant performance
- Turf grass species selection and management concepts
Irrigation and Trees and Shrubs
- Irrigation fundamentals and how water management interacts with soil
- Woody plant care and the grounds applications that depend on it
Insects and Disease, plus Chemical and Fertilizers
- Pest and disease recognition and management approaches
- Safe, correct handling and application concepts for chemicals and fertilizers
Management and Full Review
- Operational and supervisory topics drawn from your own experience
- Timed run-throughs of 75 questions in 90 minutes
The soils-first ordering is deliberate: soil knowledge underpins turf, irrigation, plant health, and fertilization, so it makes later subjects easier to absorb. Management comes last because it draws heavily on experience you already have. For a full study approach, see CGM Study Guide 2026: How to Pass on Your First Attempt, and keep the CGM Cheat Sheet 2026: One-Page Review of Must-Know Facts handy for the final days.
Key Takeaway
Finish your content review before your 30-day window opens, then use the window itself for proctor scheduling, a technology check, and a final timed practice run. Take a few full-length attempts on the CGM practice test to confirm you are consistently near the 80% mark.
Renewal Timing After You Certify
Certification is not permanent. The credential renews every three years, and renewal requires 25 CEUs, with at least 80% of them PGMS-approved. The renewal fee is $75, reduced by $25 for each year of PGMS membership. Because the three-year cycle begins once you are certified, spread your CEU activity across the cycle rather than cramming it into the final months.
Maintenance details are published on the PGMS maintaining-certification page, which is worth bookmarking so you can track your own cycle. If you are weighing whether the ongoing commitment pays off, see Is the CGM Certification Worth It? Complete ROI Analysis 2026 and the CGM Salary Guide 2026: Complete Earnings Analysis.
Verifying Current Dates and Rules
Certification programs update their procedures, and some details in the public materials conflict. For example, the current PGMS web page describes the portfolio presentation at 150-200 slides, while the official handbook says 125-200. When sources disagree, the safest move is to confirm with PGMS before you commit time or money.
- PGMS Certified Grounds Manager page: the primary overview of the credential.
- PGMS certification handbook: the detailed procedures document, with annotations dating to 2022.
- PGMS maintaining-certification page: renewal, CEU, and fee details.
Our reviewed public sources are current as of September 29, 2026, but your own confirmation with PGMS should be the final word on timing. If you are still getting oriented, What Is CGM Certification? and the broader CGM Certification overview give helpful background.
