Elementary and Secondary Education Act
The act was originally authorized through 1965; however, the government has reauthorized the act several times since its enactment—often well after the expiration of the previous reauthorization. The reauthorization of ESEA by President George W. Bush was known as the No Child Left Behind Act of 2001. ESEA was reauthorized on December 10, 2015 as the Every Student Succeeds Act (ESSA) by President Barack Obama.
Secondary education
In 1972 the school leaving was raised to 16. The Education and Skills Act 2008, when it came into force in the 2013 academic year, initially required participation in some form of education or training until the school year in which the child turned 17, followed by the age being raised to the young person's 18th birthday in 2015. This was referred to as raising the "participation age" to distinguish it from the school leaving age which remains at 16. Thus the UK is following the ISCED Level 3 (Upper) secondary education guideline.
