The Welsh government aims to get Wales in PISA's top 20 countries by 2015, the education minister told AMs on 13 November 2012.
Wales ranked 38th for reading, 40th for mathematics and 30th for science when the tests for 15 year olds were carried out last in 2009.
Whilst recognising that the target is ambitious, Leighton Andrews AM stressed his commitment to the challenge.
"I am determined that Wales can and will make the reforms necessary to make real progress towards them.
"Systematic change takes time and continued effort but has lasting effect and is sustainable."
"I want all learners to leave school with the skills they need to support their future choices and to enable them to reach their full potential," he added.
Liberal Democrat AM Aled Roberts called for more clarity on how the pattern of change would work.
Speaking on behalf of the Conservatives, Angela Burns AM criticised the minister's announcement for being "a nice statement that doesn't represent actions".
Plaid Cymru Education Spokesperson Simon Thomas questioned why the minister was introducing penalties for parents when their children missed school as Estyn advises that "rewards work particularly well, especially in attendance."
