Over the last 40 years, there have been numerous changes in the Jamaican education system at both the primary and secondary levels. In 2015, there was the introduction of the science, technology, engineering and mathematics (STEM) curriculum to meet the changing needs of industry. In order for policymakers to be able to evaluate the impact of this STEM-based programme, it is vital that the current landscape be surveyed to provide critical baseline data. This was a cross-sectional study aimed at determining the top performing STEM Academy and assessing its academic status when compared to two traditional academic institutions based on analysing the performance of their students in the Caribbean Secondary Education Certificate (CSEC) Examinations in the years 2015 and 2016. This paper provides information on baseline measures and techniques essential to the future evaluation of the achievements of this initiative; thus guiding the decision-making process.
