23Refined area based score

#### 23 Refined area based score (1) For the purposes of subparagraph 21(3)(b)(i), and without limiting that subparagraph, the Minister may be satisfied that it is not reasonably practicable to use the average DMI score for the school if: (a) there is less than 3 years of information to calculate the average DMI score for the school for the year; or (b) the number of persons responsible for students at the school for the year is too low to ensure that the CTC score does not identify information relating to a particular student or a person responsible for that student; or (c) the information available to calculate step 2 of the method statement for the DMI score does not meet the standards in the document titled Capacity to Contribute Data Validation and Quality Assurance Process published by the Department and as in force from time to time. > Note: The Capacity to Contribute Data Validation and Quality Assurance Process document could in 2020 be viewed on the Department’s website (http://www.dese.gov.au). Refined area based score (2) The refined area based score for a school for a year is worked out using the following formula:  (3) A number worked out under subsection (2) must be rounded to the nearest whole number, rounding up a number that ends in .5. (3A) However, if, for 2022 or a later year, the number worked out under subsection (2) for a small school or a very small school for the year is 3 or more higher or 3 or more lower than the school’s CTC score for the previous year, the refined area based score is taken to be 2 higher or 2 lower (as applicable) than the school’s CTC score for the previous year. Working out the school’s average SES dimension score for an SES dimension (4) The school’s average SES dimension score for an SES dimension is, subject to subsection (5), worked out by: (a) adding, for each residential address represented in the latest statement of student addresses, the SES dimension score for the SES dimension of the Statistical Area Level 1 to which the address has been assigned; and (b) dividing the result by the total number of those SES dimension scores. > Note: The SES dimension score of a Statistical Area Level 1 for an SES dimension: (a) is worked out by the Department; and (b) could in 2020 be viewed on the Department’s website (http://www.dese.gov.au). (5) In working out an average SES dimension score under subsection (4), the Minister may include a residential address in the school’s statement of student addresses that was not included in that statement, but the Minister considers ought to have been.
