Just to insert a couple points I’ve learned about education…
Environment is everything. If your kids are being bullied or distracted all day by kids who have no desire (or limited ability) to learn, I guarantee you they won’t learn nearly as well as they are capable of. A district with low test scores and other questionable stats is a direct reflection of the learning environment.
The thing that will carry your child through school, regardless of school stats, is PRE-school parent participation which continues throughout high school. If your children start kindergarten without knowing how to read, you’ve already failed them and need to get on the ball. Not because they need to know how to read in kindergarten, but because the reading and writing skills you master in elementary school determine how well you write as an adult, and getting a head start on this is vital.
