Article Summary
Addressing his Conservative party in October 2015, British Prime Minister David
Cameron called for a major overhaul of the country's public school system by endorsing
a nationwide conversion to charter-type public schools called academies while also
urging current and would-be educators across the country to create small, new
academies known as free schools. In a nationally televised broadcast, Cameron stated
"So my next ambition is this five hundred new free schools. Every school an
academyand yes local authorities running schools a thing of the past." Cameron
believes that the current system denies opportunities to British children, and the country
will not continue to thrive unless it greatly improves the talent and experience of its
younger generation.
