The Estimation Of Polytomous Item Response Models With Many Dimensions, Nikolai Volodin, Ray J. Adams
Assessment and Reporting
Identification conditions and an improved estimation method for a D-dimensional mixed coefficients multinomial logit model are discussed. This model is a generalisation of the Adams and Wilson (1997) random coefficients multinomial logit and it can be used to fit multdimensional forms of a wide range of Rasch measurement models. The computational demands of the numerical integration required in fitting such models have limited previous implementations to three and perhaps four-dimensional problems (Glas, 1992; Adams, Wilson and Wang, 1997). This paper illustrates a Monte Carlo integration method that permits the estimation of models with much higher dimensionality. The example in …

Fair And Meaningful Measures? A Review Of Examination Procedures In The Nsw Higher School Certificate, Geoff N. Masters
Assessment and Reporting
In September 1997 the New South Wales government introduced a number of significant reforms to the Higher School Certificate (HSC). The broad objectives of the 'new' HSC, which was implemented for the first time in 2000-01, are to increase the rigour and quality of the HSC curriculum; ensure HSC marks fairly reflect the standards achieved by students; provide more informative reports of students' HSC achievements; and enhance the chances for more equitable educational outcomes. Although the new HSC incorporates reforms of both HSC curricula and methods of assessing and reporting student achievement, the focus of this review is on new …
