If you're homeschooling in Colorado, you're working inside a moderately regulated framework with enough structure to keep the state informed but plenty of room to build a family-shaped program. Compulsory attendance in Colorado covers children ages 6-16, which means a homeschool program needs to be in place for any child in that range.

The instructional requirement in Colorado is defined in two dimensions: 4 hours of teaching per day, times 172 days in the school year. Parents build a schedule that fits their household. Some days are heavy on formal lessons, others rely on field trips, co-ops, or project-based learning, and all of it contributes to the yearly total of roughly 688 hours.

Notice filing is the gateway for Colorado homeschool families: a short document submitted to your local school district sets the record straight for the year ahead. Most districts accept a straightforward letter listing each student, their grade level, and a brief statement of intent.

Assessment in Colorado takes the form of parent's choice (testing, portfolio, or evaluation) at specified grade levels. It's more of a pulse-check on how learning is landing than a pass/fail exam.

The required subjects in Colorado (reading, writing, speaking, math, history, civics, literature, science, and constitution) form the backbone of each year's plan, with real freedom in how deeply or creatively each is taught. The record-keeping side of homeschooling doesn't need to dominate Colorado families' evenings. Homeschool Fox lets you log activities as they happen, then builds the compliance picture on its own.
