When to start ACT prep: A month-by-month timeline for Atlanta-area students

Parents in Athens ask me this often: “When should my student start preparing for the ACT?” The answer is simpler than most families expect. Start at the right time and a student has room to prepare properly, to retake the test if needed, and to avoid the last-minute scramble that sinks a lot of scores.

Below is a month-by-month timeline for Georgia high school students, built around local school calendars and ACT test dates.

The ideal starting point: sophomore spring or junior fall

The best time to start is the spring of sophomore year or the fall of junior year. That gives the longest runway and lines up with the better test dates and school schedules.

A sophomore-spring start means a diagnostic, targeted work over the summer, and a first ACT in the fall of junior year, when colleges start paying attention and there’s still time to raise the score. A junior-fall start still leaves plenty of time, but the schedule is tighter and each week asks for more.

Starting before sophomore spring rarely helps. The ACT tests skills that grow out of high school coursework, and most sophomores haven’t finished the algebra, geometry, and science courses the test is built on. Start too early and the student spends frustrating hours on material school hasn’t reached yet.

Month-by-month breakdown

March to April (sophomore year): diagnostic & decision

Take a full-length, timed diagnostic ACT under real conditions. If your student hasn’t taken an SAT diagnostic, do that too, compare the two, and decide which test to prioritize. This is also when to decide whether self-study, a group course, or private tutoring suits your student.

May to June (sophomore year): foundation building

Start content review aimed at what the diagnostic found, beginning with the gaps that cost the most points. For most students that means grammar and punctuation rules for English, core algebra and geometry for Math, and passage-reading strategy for Reading. If your student plans to take the optional Science section, add data interpretation practice. Hold off on practice tests until the foundation is in place.

June to August (summer before junior year): intensive preparation

Summer is the most productive window. Students in Oconee County, Clarke County, and around Athens have no homework, no extracurricular conflicts, and no exams competing for their attention. This is the time for steady sessions, ideally two to three a week, that mix content, strategy, and timed practice.

Register for the September ACT over the summer. Registration deadlines for fall dates typically fall in mid-August, and the popular test centers around Athens fill up quickly, so don’t leave it to the last week.

September (junior year): first official ACT

Sit the September ACT for a baseline official score. Take it seriously, not as a “throwaway,” but expect it to be the first of two or three sittings. It shows how your student performs under real test-day conditions, which no practice test fully reproduces.

October to November (junior year): targeted review

Go through the September score report in detail: which sections improved from the diagnostic, which held flat, which dropped. Adjust the plan to match. From here the work narrows to specific skills and specific gaps. Register for the December ACT as the second sitting.

December (junior year): second official ACT

Take the December ACT. For many Georgia students this is the date that produces the highest score, because it follows two full cycles of preparation and one real test day. Students who began preparing in the spring or summer will have had eight to nine months of targeted work by now.

February to April (junior year): final attempt if needed

If your student hasn’t reached the target, the February or April ACT is the last good chance before application season begins in earnest. By now the work should be pacing, error reduction, and stamina, with no new content. April is the last comfortable date before end-of-year exams, AP tests, and the start of applications take over.

Georgia-specific considerations

A few things about the Georgia school year affect ACT timing:

• ACT test dates in Georgia typically include September, October, December, February, April, June, and July. Not every center offers every date, and the popular ones around Athens and Oconee fill up weeks before the registration deadline, especially in the fall.
• Oconee County and Clarke County school calendars have different break schedules. Oconee schools typically start earlier in August, so students get a few weeks to settle into the year before the September test. Clarke County starts on a similar timeline but may have exam schedules that affect December preparation.
• AP course loads in junior year matter a lot. Many Athens-area students take three to five APs as juniors, which makes September through May very heavy. Students with big AP loads should lean on summer preparation and the September or December dates, before the AP work peaks.
• Georgia’s HOPE Scholarship doesn’t use ACT scores; eligibility is based on GPA. A strong ACT score still opens merit scholarships at UGA and other Georgia schools that go well beyond HOPE, so the test bears directly on what college costs.

Warning signs you started too late

If any of these describe your student, start now:

• It is the spring of junior year and they have not taken a single official ACT or SAT.
• Their first test date is less than six weeks away and they have not completed a full diagnostic.
• They are scoring more than 5 points below their target composite and have not started structured preparation.
• College application deadlines are within four months and they do not yet have a score they are willing to submit.

None of these is hopeless. A compressed timeline can still produce a meaningful improvement, but it takes more frequent sessions and more of the student’s time and energy than the ideal timeline would. Starting earlier buys room to maneuver.

Where private tutoring saves time

Self-study works for students who are disciplined, already near their target, and able to diagnose their own weaknesses. For everyone else, a private tutor shortens the timeline by cutting out the hours lost to studying the wrong material, practicing without feedback, and repeating mistakes without knowing why.

What a good tutor adds is a diagnosis that finds the real problems rather than the assumed ones, a plan that changes as the student improves, and someone checking the work every week. I don’t prep the ACT as a whole, though I’ll work its math section case by case; the same approach is how I run SAT prep.
