Overhauling the Welsh education system is going to take time and patience.
Education minister in the Welsh government Huw Lewis stated there are no "quick fixes" when it comes to improving standards across the board.
Speaking to BBC Wales, Mr Lewis said the country is currently on an "education improvement journey" that is expected to take more than a couple of years to get right.
"Everyone from myself to leaders of local authorities, teachers, school governors - everyone needs to ... recognise the challenge is for them," he added.
The politician was speaking after the latest Programme for International Student Assessment tests were released by the Organisation for Economic Co-operation and Development, which saw Wales ranked as the worst country in the UK in three separate subjects - science, maths and reading.
With significant reforms introduced around a year ago, Mr Lewis expects to see gradual improvements in the performance of pupils in the nation.
