PISA is an international study that was launched by the OECD in 1997. It aims to evaluate education systems worldwide every three years by assessing 15-year-olds’ competencies in the key subjects: reading, mathematics and science. To date over 70 countries and economies have participated in PISA.
From the data available in the PISA Test, Andreas Schleicher shares his ideas of why some schools countries’ educational systems succeed better than others. What it quickly boils down to is not how much money needs to be spent to improve the educational system. It is more important that whatever resource each nation has is spent wisely and appropriately. A small class room size might be more conducive for learning as some might think but if the costs of maintaining those small numbers mean that there is no investment made on professional development for teachers, then the system fails in allocating resources properly.
