“Cohort Survival Rate” and other terms used in education statistics
officially-defined by NSCB
(PR-200701-SS2-01, Posted 04 January 2007)
Do you know what “cohort survival rate” means? Cohort Survival Rate is a measure of the efficiency and effectiveness of the delivery of education services in the country, and is defined as the percentage of enrollees at the beginning grade or year in a given school year who reached the final grade or year of the elementary or secondary level. Based on this definition, the cohort survival rate at the elementary level in the Philippines declined from 64.9% in SY 2004-2005 to 62.6% in SY 2005-2006. This means that from a cohort or group of 100 Grade 1 pupils, only 62 pupils reached Grade 6.
The Cohort Survival Rate is one of 28 major statistical indicators commonly used in education statistics which have been defined by the National Statistical Coordination Board (NSCB) through Resolution Number 14, Series 2006, “Approving and Adopting the Official Concepts and Definitions for Statistical Purposes for the Education Sector”, and Resolution Number 15, Series 2006, “Approving and Adopting Six Formulas on the Official Concepts and Definitions for Statistical Purposes for the Education Sector” for adoption in the Philippine Statistical System (PSS). This is in accordance with the mandate of the NSCB to ensure the harmonization and comparability of statistics in the country.
The term “cohort survival rate” is one of the core statistical indicators used in the Medium Term Philippine Development Plan (MTPDP), in the Millennium Development Goals (MDGs), and in the Education For All (EFA) global movement, among others. Based on latest estimates, the Philippines has a low probability or likelihood of attaining the target of universal primary education as the computed annual growth rate from 1991 to 2005 shows an annual decline of 1.3% versus the required annual growth rate of 4.0%. The achievement of this specific MDG by 2015 will thus need a reversal of trends and the country’s educational system has a lot of catching up to do.
The definitions and formulas of these major statistical terms, together with the definitions of other commonly-used terms in education statistics, are contained in a new publication entitled “Glossary of Commonly Used Terms in Education Statistics” for release on January 5, 2007. The glossary, an output of the NSCB Inter-Agency Committee on Education Statistics (IACES), is an initial step towards the harmonization and standardization of terms used in education statistics and is envisioned as a reference material for planners, decision makers, and researchers, as well as basis for future legislation.
The IACES is composed of representatives from the three pillars of education, namely; Department of Education; Technical Education Skills and Development Authority; and the Commission on Higher Education; as well as other national government offices such as the National Economic and Development Authority, National Statistics Office, Philippine Science High School, Science Education Institute, National Commission for Culture and the Arts, Professional Regulation Commission, Statistical Research and Training Center, Senate Committee on Education and the NSCB. The NSCB acknowledges the contributions of CHED which financed the greater part of the collaborative work for the Glossary.
