The three deadline waves
Senior-year college admissions in the US follow three deadline waves: the early-action and early-decision wave on November 1 and November 15, the regular-decision wave on January 1 and January 15, and the rolling-admissions and scholarship wave through March. Each wave has its own document requirements, fee deadlines, and recommendation-letter deadlines.
Build the deadline calendar in August
The right time to print the senior-year college deadline calendar is the first week of August, before classes start. Print the September through March monthly calendars and mark every deadline with the school name, deadline type, and a one-line list of what is required. The result is one printed planning surface that drives the entire fall and winter.
Recommendation letters
Recommendation-letter requests should go to teachers in the first two weeks of September, not the first two weeks of October when every other senior is asking. Mark the request date and the followup-thank-you date on the printed calendar. The teacher is more likely to write a thoughtful letter when the request comes early and quietly.
FAFSA and CSS Profile
The FAFSA opens October 1 every year. The CSS Profile opens slightly later. Both should appear on the printed calendar as deadlines, not as start dates — the right behavior is to complete them within the first two weeks of opening, not at the spring deadline. Schools that use rolling admissions or rolling scholarship review reward early submitters.
The decision window
Decisions arrive between mid-March and early April. National decision day is May 1. Print the March, April, and May monthly calendars at the start of senior spring and protect the two-week window between the last decision and May 1 — that is the family's actual decision window. It is shorter than people expect and benefits enormously from being marked clearly on a printed calendar.
