Improving education is key to promoting a sustainable development and is emphasised in current global international agendas such as the Sustainable Development Goals (i.e., Goal 4). However, the lack of tailored scales to assess year-1 primary school pupils, remains as a major concern in the Latin American region and more specifically in Mexico. This pilot study seeks to adapt and test the International Performance Indicators in Primary Schools assessment (iPIPS, www.ipips.org, Tymms, Merrell & Buckley, 2016) in Mexican. This assessment will measure year-1 students’ cognitive/academic skills in language, early reading, early mathematics and phonological awareness at the start and the end of the year. This instrument will provide Mexican policymakers with high quality assessments, which could be used across 32 states in Mexico, providing reliable and comprehensive evidence for policymakers and help in interpreting the results of international assessments such as TIMSS and PISA.
