What state are you in? We’re NYS homeschoolers. When my son applied to colleges he had to show that he completed a program that was the substantial equivalent of a high school education (4 years each of Eng, math, lab science, history, and foreign language). We needed to provide one of the following as proof: documentation from the district we reported to, results from several (specific) NYS Regents exams, 24 (specific) college credits, or a passing GED score. You need to know what your state requires of homeschoolers AND what each college you’re interested in requires.
@citymama9 is incorrect that homeschoolers have to submit SAT subject tests. What they have to submit varies by school. My son had to send his SAT scores, copies of all his grade 9-12 report cards and our yearly Individualized Home Instruction Plan, a description of every course he took, and a complete list of materials and texts. Make sure you carefully study the requirements of each college you’re interested in and run their Net Price Calculator to make sure they’re affordable.
Our area homeschoolers have been accepted to a broad range of colleges – Penn State, SUNYs, RIT, RPI, Harvard, Bard – the key is to understand what documentation they want and make sure they get it. Good luck.
