Unit Overview


This unit introduces students to advanced principles of Rasch measurement theory in the social sciences. It is a follow-up to EDUC5638 Introduction to Classical and Rasch Measurement Theories (formerly EDUC8638 Introduction to Rasch Measurement of Modern Test Theory). Topics include fundamental measurement, elementary discrete probability distribution theory, Dichotomous Rasch Model (review of principles; multiple-choice items and guessing), Polytomous Rasch Model, differential item functioning (DIF), fit of responses to the model (analysis of residuals), violations of the assumption of independence (multidimensionality and response dependence, estimating the degree of dependence), analysis of more than two facets, and reporting a Rasch analysis. The unit is delivered entirely online and students study at their own pace. Students receive (1) the study guide, (2) a set of lecture materials, (3) details of the assignments, and (4) selected readings. Students and staff participate in online discussions.

6 points

Students are able to (1) explain different approaches to measurement including the traditional and modern approaches; (2) explain advanced principles of Rasch measurement theory in the social sciences; (3) use a range of diagnostic tests in order to assess the quality of achievement, knowledge and attitude; (4) write up a Rasch analysis for publication; and (5) apply specialised software in analysing assessment and attitude data.


This comprises seven assignments (total 55 per cent) and one major project (45 per cent). Supplementary assessment is not available in this unit.

Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
  • Contact hours provide an indication of the type and extent of in-class activities this unit may contain. The total amount of student work (including contact hours, assessment time, and self-study) will approximate 150 hours per 6 credit points.
