When you homeschool high school, three months can equal one year - when your kids are doing dual enrollment at a local community college. Dual enrollment is offered to students in many states. It provides high school and university credit at the same time. Homeschoolers take advantage of dual enrollment to help defray higher education expenses by allowing students the opportunity to earn university credit while still homeschooling.

"3 months equals 1 year" because in a community college, they don't spend a whole year going through a textbook. They'll spend three months, instead. For example, they might take only three months to got through a level of French that would normally take a full year in homeschool. Similarly, in high school American History, it takes a whole year to get a credit. At a university, you can finish the course in a quarter or semester. In addition, students will usually just take three full courses at a time, then three months later they take another three classes, and then another three. In the upper grades, almost everyone takes more classes than that. In high school, calculus covers... well, calculus. In a year of college calculus, students might cover calculus 1, calculus 2, and multivariable calculus. And so that is why...

What a secondary school calls one credit will be covered in one year, while a college will cover the same material in three months and call it 5 credits. In other words, three months at a university can equal one whole year of high school.

Each university has it's own way of translating community college credits into their credits, and some don't take such credits at all. However, if you are looking to try to reconcile college credits onto your homeschool transcript, you may want to consider the "5 college credits = 1 high school credit" equation to help you on your transcript.
