This paper aims to analyse the applications for raising students' and schools' academic performance in the context of equal opportunities in education in such countries as Canada, Finland and Singapore with high achievement in PISA (Programme for International Student Assessment) in 2018 and thus to make recommendations to our country- Türkiye. A qualitative study method was used in this current study. Document analysis technique, a method of qualitative study, was used in collecting the data. The data collected were then described under certain headings through descriptive analysis. The applications for raising academic performance in the context of equal opportunities in education in certain countries with high achievement in PISA (2018) were analysed under the headings of "applications of academic support for students in the context of equal opportunities in education in the countries" and "applications of academic support for schools in the context of equal opportunities in education in the countries". It was found in consequence that mostly local or school-based applications were available for students and schools in the countries. It is evident that applications are performed within a system. Interventions are made according to feedback. All the stakeholders take on active roles in the process. More systematic and local configuration involving all the stakeholders is needed in our country.
