How to choose?
— now that there is a choice.
Do school districts choose today's school system?
Not really.
It is simply the way things have always been done.
The last time districts intentionally chose a system (today's system) was in 1913 — as documented by Raymond E. Callahan in Education and the Cult of Efficiency.

So now, there is the opportunity to choose.
Now today's system can be chosen, not just inherited.
Or, superintendents can choose to allow volunteer educators to learn and apply the Lead Out Method.
Let's make a conscious choice.
Begin with Today's school system.
Then, if you choose, explore the Lead Out Method.
