I would like to see an expansion of the existing education marketplace, to reduce the monopolistic effect of the State, and ensure that more choices are available to students, parents (and teachers). This should not be driven by bureaucrats, politicians or trade unions, but from the ground up.
Remove the barriers to peoples own needs, desires, and agency/energy. I am not arguing against the comprehensive model, just that it compete with other models/providers on more equal terms. The State would remain crucial, as funder, monitor and facilitator, but be the brain of the system, and not the brawn by also monopolizing provision.
In a word, my approach is person centered, rather than state centered. Call me radical, and naive, but I believe in people, and the individual human right to autonomy of beliefs and practices, including education (as long as these do not infringe on the human rights of others).
