Private Education Validation Guide A “Two Steps” easy to follow guide, prepared by the ICP Regional Team for Western Asia Region Private Education Validation Guide

Validation Guide’s Outline Intra-country data validation Inter-country data validation

1-The Intra-country Validation Devised specifically for the Private Education survey questionnaire.

The Intra-country Validation 1.1 - The General Education Indicators sheet Checking that the GEI sheet was fully filled in: 2011 data was provided; Age school population; The number of students in private and public schools; The number of private and public schools. N.B: Numbers should be provided in thousands.

The Intra-country Validation 1.2- Data Collection Form sheets It is necessary to check the DCF sheets, each of them is divided into two sections: - Box A includes the National Standard Information - Box B includes Information for Each Observations

The Intra-country Validation 1.2- Data Collection Form sheets Box A: National Standard Information Starting and ending dates of the academic years: 2010/2011 and 2011/2012. mm/dd/yy 140 days < Number of school days < 180 days

The Intra-country Validation 1.2- Data Collection Form sheets Box B: Information for Each Observations Number of observations: '2. Survey Frame' of the Private Education Guidelines published by the GO & prices collected should represent all types of private schools in the country. Observation details Course fees should be annual or hourly Contradictions should be eliminated Explanatory note

Oman is the base country

2-The Inter-country Validation Characterized by the construction of Special Private Education Average Price files, and special Quaranta tables.

The Inter-country Validation 2.1 THE QUARANTA TABLE In order to be able to create a QT, special files had to be constructed: Average price files, averaging the observations of the countries, after performing the intra-country price validation. Complementary files (Population, Nominal expenditure and Exchange rate files), borrowed from the Annual HHC complementary files.

The Inter-country Validation 2.2. The Actual Validation The Price Level Index (PLI): It expresses the price level of a given country relative to another; In the Private Education survey case, PLI is calculated for one BH; During the initial data validation, focus is normally on correcting the extreme errors.

The Inter-country Validation The Coefficient of Variation (CV) Country CV: the higher the CV’s value the less uniform the country’s price levels will be, leading to less reliable PPPs. N.B: In the case of Private Education survey, it is normal to have high CV since the 7 compared items can normally diverge in prices. BH CV: the higher the CV’s value, the less homogeneous the price structures will be, resulting in less reliable PPPs.

The Inter-country Validation Check for price discrepancies through the colored scale of the Quaranta table.

The Inter-country Validation Potential Sources of error Price discrepancies can result of: Data entry errors; Difference in the item specifications; The number of days that fall in the calendar year 2011.

The Wrap up THANK YOU Countries should review the data according to the comments given during the actual validation session and return a clean Database to the RO.
