Short answer: pick your exam date first, then start studying 12 to 16 weeks before it. If you have no exam date, the honest answer is that you have not started deciding yet, and that is the thing to fix this week. Not with a study plan. With a date.

I am going to say the quiet part out loud, psychologist to psychologist. Most people who ask "when should I start studying" are not asking a scheduling question. They are in precontemplation about their own exam. The EPPP sits in the "after I settle in at my postdoc" pile, and the pile never shrinks, because supervised practice never gets less busy. You know exactly what this pattern is. You have billed sessions for it.

The cost of "later" is not zero

Waiting feels free because nothing bad happens this week. But the meter runs quietly. Every month before licensure is a month at supervised-practice pay, and the gap between that and licensed pay is usually thousands of dollars a month. I did the arithmetic in how much an unlicensed year costs a psychologist, and it reframes the whole question. "When should I start" stops meaning "when is convenient" and starts meaning "how much longer do I want to pay for not deciding."

That is not a guilt trip. It is decisional balance, and you would run the same exercise with a client: list what waiting buys you, list what it costs, and look at both columns honestly. For most postdocs the waiting column contains one real item, "I am busy," and the cost column contains a mortgage payment per month.

Working backwards from the license

Here is the order of operations that actually works:

1. Pick the quarter you want to be licensed in. Not the exam, the license. Check your board's timeline for what has to happen after you pass.
2. Set the exam date 12 to 16 weeks out from today, or as close to that as your board's authorization process allows. If you are weighing this month against next, the tie goes to sooner. I wrote about that tradeoff in should you take the EPPP now or wait.
3. Take a diagnostic before you study anything. Your baseline decides your timeline, not the other way around. A strong baseline can shorten 16 weeks to 10. A rough one just means the plan starts from the truth. Mine started at 19%.
4. Then build the weekly plan. For most people working full time that is 6 to 8 real hours a week, and the week-by-week version is in the 12-week postdoc study plan.

Notice what is not in the list: waiting until you feel ready. Feeling ready is a product of studying, not a prerequisite for it.

But how early is too early?

There is one genuine reason to wait: if you are more than about 6 months from being able to sit the exam, a full study push now will decay before test day. In that case, start the light version, occasional practice questions to keep the material warm, and save the focused 12-to-16-week push for when the date is real.

There is no such thing as too late to start deciding, though. Even people 4 weeks out do better with a plan than with panic. The plan just gets more surgical.

Frequently asked questions

How many months before the EPPP should I start studying? Three to four months of focused study is the standard window for people working full time, which is why 12 to 16 weeks backward from your exam date is the practical rule. Longer than 6 months of active prep tends to leak retention.

Should I wait until my postdoc ends to study for the EPPP? For most people, no. Postdoc life does not get quieter, and delay has a real monthly cost. A 6-to-8-hour weekly plan is built to survive a full-time schedule.

Can I study for the EPPP before my board approves me to sit? Yes, and taking a diagnostic early is useful no matter where your paperwork is. Just anchor your focused push to a real or realistic exam window so the material peaks at the right time.

How do I know if I am ready to set a date? Backwards question. Set the date, then take a diagnostic to find out what the date requires of you. Readiness is what the next 12 weeks are for.
