This paper will describe the process of data collection and analysis undertaken in two NSW schools to extend the Australian Item Response Modelling (IRM) data for a series of mathematics tests covering six year old to 14 year old children. In the project, students in two Sydney schools were tested with Maths 12, or 13 or 14 [Y0] tests according to their chronological age at date of testing. Each student also took the Maths 11 [Y0] test as well, to allow statistical analyses with Quest software [ACER 1996] to created extensions to the profiles already published for Australian teachers by Professional Resources Services [PRS] for Maths 7 - 11 [YO]. The extension data will be publicly released at the time of presentation of this paper. Discussion will focus on, the diagnostic and curriculum planning possibilities facilitated by the testing and IRM analyses to encourage and allow "Testing for Teaching Purposes".
