A significant benefit of the new identification process for DEIS Plan 2017 lies in its capacity as a uniform system adopting common criteria and a consistent application across all primary and post-primary schools.
The identification process used two key data sources namely the DES Primary Online Database (POD) and Post-Primary Online (PPOD) Databases, and CSO data from the National Census of Population as represented in the Pobal HP Index for Small Areas which is a method of measuring the relative affluence or disadvantage of a particular geographical area. Variables used in the compilation of the HP Index include those related to demographic growth, dependency ratios, education levels, single parent rate, overcrowding, social class, occupation and unemployment rates. This data is combined with pupil data, anonymised and aggregated to small area, to provide information on the relative level of concentrated disadvantage present in the pupil cohort of individual schools. This data is applied uniformly across all schools in the country.
