Unit Overview


This unit begins with an introduction to the historical development of test theory and how modern test theory has superseded traditional test theory in many applications, especially in large-scale assessments. In particular, students learn how Rasch measurement incorporates, elaborates and better achieves the goals of traditional test theory. The unit includes lectures on the formalisation and calculation of traditional reliability and reliability in Rasch models, the concept of validity in both traditional and modern test theory, the concepts of invariance and sufficiency in Rasch measurement, diagnosing the fit of responses to the Rasch model, and the Rasch model for dichotomous items and for items with ordered response categories.

6 points

Students are able to (1) explain the basic principles of Rasch measurement theory in the social sciences; (2) understand the principles of traditional test theory in terms of Rasch measurement theory; (3) use a range of diagnostic tools in order to assess the quality of items in constructing assessment instruments of achievement, knowledge and attitude; and (4) apply software in analysing assessment data.

  • 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.
