Philippines School enrollment, preprimary (% gross)

Data:	School enrollment, preprimary (% gross)
Year:	1960 - 2013
Country:	Philippines
Source:	World Bank (the information in this section is direct quotation from World Bank development data)
Series Code:	SE.PRE.ENRR
Topic:	Education: Participation
Short Definition:	0
Long Definition:	Gross enrollment ratio is the ratio of total enrollment, regardless of age, to the population of the age group that officially corresponds to the level of education shown. Preprimary education refers to the initial stage of organized instruction, designed primarily to introduce very young children to a school-type environment.
Unit of Measurement:	0
Periodicity:	Annual
Base Period:	0
Reference Period:	0
Aggregation method:	Weighted average
Limitations and exceptions:	Overage or underage enrollments are frequent, particularly when parents prefer children to start school at other than the official age. Age at enrollment may be inaccurately estimated or misstated, especially in communities where registration of births is not strictly enforced.

Statistical concept and methodology:	Enrollment indicators are based on annual school surveys, but do not necessarily reflect actual attendance or dropout rates during the year. Also, the length of primary education differs across countries and can influence enrollment rates and ratios, although the International Standard Classification of Education (ISCED) tries to minimize the difference. A shorter duration for primary education tends to increase the ratio; a longer one to decrease it (in part because older children are more at risk of dropping out). Gross enrollment ratio for preprimary school is calculated by dividing the number of students enrolled in preprimary education regardless of age by the population of the age group which officially corresponds to primary education, and multiplying the result by 100. Aggregate data are estimates by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) Institute for Statistics (UIS). Population data are drawn from the United Nations Population Division. Using a single source for population data standardizes definitions, estimations, and interpolation methods, ensuring a consistent methodology across countries and minimizing potential enumeration problems in national censuses. Data on education are collected by the UIS from official responses to its annual education survey. All the data published by the UIS are mapped to the International Standard Classification of Education 1997 (ISCED97). This classification system ensures the comparability of education programs at the international level. UNESCO developed the ISCED to facilitate comparisons of education statistics and indicators of different countries on the basis of uniform and internationally agreed definitions. First developed in the 1970s, the current version was formally adopted in November 1997. The reference years reflect the school year for which the data are presented. In some countries the school year spans two calendar years (for example, from September 2010 to June 2011); in these cases the reference year refers to the year in which the school year ended (2011 in the example).
Development relevance:	Enrollment indicators help monitor whether a country is on track to achieve the Millennium Development Goal of universal primary education by 2015, and whether an education system has the capacity to meet the needs of universal primary education. Gross enrollment ratios indicate the capacity of each level of the education system, but a high ratio may reflect a substantial number of overage children enrolled in each grade because of repetition or late entry rather than a successful education system. The net enrollment rate excludes overage and underage students and more accurately captures the system's coverage and internal efficiency. Differences between the gross enrollment ratio and the net enrollment rate show the incidence of overage and underage enrollments.
