If you're the parent of a high school junior or senior, the college planning calendar can feel like ten parallel deadlines you didn't know existed. This is the month-by-month timeline we wish more families had. It covers junior year (when most leverage actually exists) through senior-year application season, with the specific tasks that materially affect admissions and financial aid outcomes.
This timeline assumes a student aiming at a mix of selective and non-selective four-year colleges. If your student is targeting community college, trades, or a gap year, the structure still applies — just compressed. We've also written a college vs. trade school ROI guide if you're weighing alternatives.
Junior Year Timeline: The High-Leverage Year
Junior year is when the largest planning gains happen. GPA still moves, test scores can be built, course rigor decisions are still in front of you, and major exploration is still possible without rushing. By contrast, senior year is mostly execution.
August–September (Junior Year)
Confirm course rigor. Honors and AP/IB courses junior year are the single biggest academic signal to selective colleges. Register for the October PSAT/NMSQT — this is the qualifying year for National Merit Scholarship consideration. Begin a college list spreadsheet (target schools, reach schools, financial safeties). Have a first conversation about budget.
October (Junior Year)
Take the PSAT/NMSQT. Begin systematic ACT or SAT prep — most students benefit from 60–100 hours of prep distributed over 4–6 months. Visit two or three colleges within driving distance to develop a "feel" for what you like.
November–December (Junior Year)
Review PSAT score report when it returns in December. Identify weak subscores; align test prep accordingly. Begin major exploration if not already started — this is the right time to take a structured assessment like the free MajorMatch assessment. Knowing the major (or top 2–3 candidates) before senior fall makes the application essay and college-list work dramatically easier.
January–February (Junior Year)
Take the first ACT or SAT. February ACT and March SAT are typical first-attempt dates. Most students benefit from two attempts at the same test (not switching back and forth). Begin scheduling additional college visits during winter and spring breaks.
March–April (Junior Year)
Take AP/IB exams in May (registration deadline is typically March). Continue test prep and college visits. Refine the college list to 12–18 schools across reach/target/safety tiers. Begin researching scholarship opportunities — local scholarships have far better odds than national ones.
May (Junior Year)
Take AP/IB exams. Take the second ACT or SAT if scores need to improve. Request teacher recommendation letters before the school year ends — junior-year English, math, or major-related teachers are typical choices. Don't wait until senior fall when teachers are flooded with requests.
June–July (Summer Before Senior Year)
This is the highest-leverage stretch on the entire calendar. Draft the Common App personal essay over the summer. Visit final list of colleges (in-person or virtual). Begin supplemental essay drafts for any school requiring them. Take a third test attempt only if scores still need to improve. Lock the college list at 8–12 schools.
Lock In the Major Before You Lock In the Schools
Application essays, college fit, and financial aid strategy all flow from knowing the major. Take the free MajorMatch assessment to identify your student's top three majors based on their interests and strengths.
Take the Free Assessment →Senior Year Timeline: Execution
Senior year is mostly about hitting deadlines. The strategic work happened junior year. The senior year calendar below is built around the standard early-action/early-decision/regular-decision rhythm.
August–September (Senior Year)
Finalize Common App personal essay. Begin supplemental essays for highest-priority schools. The FAFSA opens October 1 — gather tax documents and prior-prior-year income records now. Confirm teacher recommendation letters are uploading. Take final ACT/SAT in September if needed for early-action deadlines.
October (Senior Year)
Submit FAFSA in the first two weeks. Submit the CSS Profile if any of your colleges require it (most selective privates do). Submit early-action and early-decision applications by November 1 deadlines — that means working drafts done in October. Most ED schools are non-binding for financial review only at scholarship-driven schools; regular ED is binding if admitted.
November (Senior Year)
Submit any remaining early-action applications. Begin regular-decision essays. Continue scholarship applications — many local scholarships have December and January deadlines. Confirm transcripts and test scores have been sent to all early-application schools.
December (Senior Year)
Receive ED/EA decisions. Submit regular-decision applications (most are due January 1, January 15, or February 1). If accepted ED, formally withdraw applications from other schools. If deferred or denied ED, move that school's regular-decision-equivalent to top of the priority list.
January (Senior Year)
Submit final regular-decision applications. Continue scholarship applications. Mid-year transcripts often need to be sent — confirm with the school counselor. Update FAFSA if any financial information has changed.
February–March (Senior Year)
Receive regular-decision letters (most arrive between mid-March and April 1). Compare financial aid offers carefully — net price, not sticker price, is what matters. The Department of Education's Net Price Calculators on each college's website can preview cost.
April (Senior Year)
This is the financial decision month. Compare offers. Negotiate aid where possible (yes, this works at many schools — especially with competing offers in hand). Visit accepted schools if not already visited. National Decision Day is May 1 — most schools require enrollment deposits by then.
May (Senior Year)
Submit enrollment deposit by May 1. Take final AP/IB exams. Withdraw waitlist applications at schools you won't attend. Send final transcript request to your matriculating college.
June–August (Summer Before College)
Complete enrollment paperwork. Sign up for orientation. Review course registration. Lock down housing arrangements. Final FAFSA confirmations. Begin connecting with future roommates and orientation cohorts.

What Most Families Get Wrong on the Timeline
Starting too late on the major decision
Families often wait until senior fall to think about the major. By then, the application essay is being drafted, the college list is mostly set, and the supplemental essays asking "why this major" are already due. Resolving the major during junior year (or earlier) makes everything downstream easier and produces stronger applications.
Confusing test-optional with test-irrelevant
Most "test-optional" colleges still meaningfully reward strong test scores in admissions and merit-aid decisions. If a student can hit the school's 75th-percentile score, submitting almost always helps. If the student is below the 25th percentile, withholding is the right move.
Treating financial aid as a senior-year topic
Financial aid strategy belongs in junior year, not senior year. The CSS Profile considers home equity, asset structure, and timing of distributions. Sophisticated families plan asset positioning 18–24 months ahead of the FAFSA filing year. Talk to a fee-only financial aid consultant during junior year if your family's situation is non-trivial.
Underestimating the value of state flagship and honors programs
Honors colleges at flagship state universities frequently deliver elite-tier academics at one-third to one-fifth the cost of comparable private schools. Families who only consider out-of-state private schools often leave $150K–$250K of value on the table.
