"GUIDELINES FOR CALCULATING A SCHOOL SES SCORE"
GUIDELINES FOR CALCULATING A SCHOOL SES SCORE Under section 8 of the Schools Assistance (Learning Together – Achievement Through Choice and Opportunity) Act 2004 (the Act), the Guidelines for Calculating a School SES Score are a legislative instrument for the purposes of the Legislative Instruments Act 2003. PART 1. Schools other than Special Assistance Schools and Special Schools SES Index The SES Index, from which the SES scores for Census Collection Districts (CDs) are derived, comprises the following dimensions - Occupation, Education and Income [½ Household Income / ½ Family (with children) Income]. Where a complete set of the four dimensions is not available (for 2001 Census - about 3% of over 37,000 CDs in Australia), because the Australian Bureau of Statistics (ABS) does not release data which could be used to identify an individual, some CDs do not have a CD SES score. [The table below shows a school SES score calculated using CDs with missing dimensions.] If these CDs were omitted altogether from the calculation of the school SES score, the score would not be truly representative of the school community and could either advantage or disadvantage the school. School SES Score In order that every geocoded address contributes to the school SES score, the score will be based on the four individual dimensions for each CD and averaged by the number of addresses for which a dimension score exists. The school SES score will then be calculated from the average of each dimension. A practical example of how a school SES score will be calculated is shown in the table below. Methodology for calculating a School SES Score 1. Calculate to 4 decimal places the average value for each of the Occupation, Education, Household Income and Family Income dimensions. Note: - the total for a dimension is averaged only by the number of addresses containing data for that dimension; and - if an address has not been geocoded and assigned to a CD, that address will not be included in the calculation. 2. Calculate the School SES score to 4 decimal places using the following formula : School SES Score = Occupation dimension / 3 + Education dimension / 3 + Household Income dimension / 6 + Income of Families with Children dimension / 6 3. A School SES score is rounded to a whole number. For example: 95.4567 is rounded to 95 95.5123 is rounded to 96.

Special Assistance Schools and Special Schools The SES score for Special Assistance Schools and Special Schools can be calculated by ascertaining the score that, for the purpose of the Tables in Parts 1 and 2 of Schedule 4 of the Act, has an associated current funding level of 70 per cent of Average Government School Recurrent Costs (AGSRC).
