In this article I report on how family variables can be included in ananalysis of the determinants of science outcomes (science achievement and attitude). The family latent factor is regarded as an essential determinant of science outcomes. The problemarises in connection with what constitutes the family factor and which variables to use in its measurement. The problem is particularly prevalent when structural equation modelling is used to analyse the determinants of science outcomes. Three aspects to this problem are presented in this article.Firstly, the identification of variables used in the literature for measuring the family latent factor. Secondly, the use of confirmatory factor analysis to test the factorial structure of the family latent factor.Thirdly, the use of the factorial structure in structural equation models of science achievement and attitude. The emphasis is on the first two aspects. The third aspect is reported elsewhere.
