Grade 12: Senior year — the final year of K–12
Senior year is the culmination of 13 years of K–12 education (Pre-K + K–12). College applications are due October–January of Senior year. FAFSA (Free Application for Federal Student Aid) opens in October. Most students graduate in May or June at age 17 or 18. Senior year also brings "senioritis" — a documented drop in motivation after college admissions are settled — which colleges monitor through mid-year grade reports. Dual enrollment (taking college courses for credit during Grade 12) is increasingly common and can save a semester or more of college tuition.
