How will you know if they're learning?
Teachers need to measure and document because they need to show progress so they can get paid, and keep their jobs. They test and measure because they don't always know each child well.
Parents know a child is learning because they're seeing and discussing and doing things together every day. Not five days a week, or most of the year, but all of the days of their whole lives.
