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 Capacity to Contribute Data Validation and Quality Assurance Process. Refined area based score (2) The refined area based score for a school for a year is worked out using the following formula: A formula to work out the refined area based score for a school for a year (3) A number worked out under subsection (2) must be rounded to the nearest whole number, rounding up a number that ends in 0.5. (4) 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. (4A) In applying subsection (4) for 2027, for a small school or a very small school, the school’s CTC score for 2026 is taken to be the number that would, but for subsection 21(4), have been the school’s CTC score for 2026. Working out the school’s average SES dimension score for an SES dimension (5) A school’s average SES dimension score for an SES dimension is, subject to subsection (6), 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. (6) In working out an average SES dimension score under subsection (5), 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.
