The SEAMEO Basic Education Standards (SEA-BES) is a regional curriculum project with the purpose of developing learning standards known as the Common Core Regional Learning Standards (CCRLS) in Mathematics and Common Core Regional Learning Standards (CCRLS) in Science. The SEA-BES CCRLS serves the goal of mproving the quality of education in the SEAMEO Member Countries through comparison and identification of gaps in terms of curriculum content (i.e. knowledge,  kills, attitudes, habits) as well as bases for assessing student learning outcomes. The SEA-BES project envisions to developing common shared and agreed standards or what every learner should know, be able to do and value in mathematics and science. The CCRLS can be used to improve the quality of SEAMEO Member Countries’ national curriculum creating equity in curricular provisions across countries and high expectations for all students and learning outcomes that will enable students to contribute productively to their individual countries and their region.

The development of the CCRLS was made possible with the participation and involvement of mathematics and science teachers and experts across the Southeast Asian region and beyond through a series of workshops conducted in-house, local level and regional level as well as international level. The CCRLS was built upon the strength of the existing standards of the SEAMEO Member Countries and further enhanced by the standards of high-performing countries on international student assessments as well as carefully studying the research and literature available on what students need to know, be able to do and value to be successful in post-secondary school, college, career and life.

The publication of SEA-BES Common Core Regional Learning Standards in Mathematics and Science serves as reference to developing the national science and mathematics curriculum of SEAMEO Member Countries in their various efforts of educational reforms. This book publication is comprised of two separate learning standards, namely; the SEA-BES Common Core Regional Learning Standards in Mathematics and SEA-BES Common Core Regional Learning Standards in Science. Both Learning Standards share the same introductory chapter “Vision of SEAMEO and Purpose of CCRLS” but only appears in CCRLS in Mathematics. Each Learning Standard maintains its own set of references.
