The OECD suggest that there is not a conclusive link to the amount of money spent per student and the results of international Pisa tests when comparing similar nations.

South Korea is one of the highest-performing OECD countries, but spends well below the average per-student expenditure, while Poland spends around $68,000 (£52,000) per student between the ages of six and 15 and performs at the same level at age 15 as the United States, which spends over $115,000 (£89,000) per student.

The OECD has instead looked at the ways in which countries fund their schools. It emphasises that transparency in school funding policies and how resources are distributed is necessary to deliver quality, equity and efficiency. It highlights the need for uniform funding levels across a system for students in similar circumstances – and, at the same time, extra funding for any additional needs of students.

Helping schools to identify spending and cost savings to better utilise their budgets is IT Asset Management solution, NetSupport DNA. It identifies areas such as how much was spent on energy from computers left on, to printing costs, underutilised hardware or software licences, plus much more. It also includes classroom management and safeguarding tools to make technology-led teaching more efficient and safe, savings teachers’ time while maximising learning outcomes.
