Abstract. 

The aim of the paper is to analyze some of the data gathered by a telephone
survey conducted, about two years after the degree, on the 2000’s graduates of
the University of Florence. The main goal is to determine the factors which
influence the way of acquisition of the skills and to evaluate the degree
programmes on the basis of the adequacy of the skills they give to their
graduates. The analysis of such data raises several methodological
questions. In order to taking into account the features of the data, a suitable
multivariate multilevel model for polytomous responses with a non-ignorable
missing data mechanism is developed and fitted by means of maximum likelihood
with adaptive Gaussian quadrature.
In the application the multilevel structure has a crucial role, while selection
bias results negligible. The analysis of the empirical Bayes residuals allows to
detect some extreme degree programmes to be further inspected.

The paper is joint work with Leonardo Grilli
