While current test scores at Delta Charter are below average, the school shows strong growth metrics — meaning students are making above-average progress year over year. This upward trajectory can be a positive indicator for families who value a school's ability to help students improve, even if absolute scores haven't caught up yet.

Parents should understand the school's specific mission, enrollment process, and how its approach differs from nearby district options.
