Abstract
The construction of the 18REST, a short 18-item inventory to describe students’ position on John Holland's RIASEC interest types, is documented. The instrument is meant to be used in large-scale assessment in education and on the labor market, supplementing information on school achievement and social-emotional skills. This research was carried out in Brazil, initially with two independent samples composed by adolescents and adults. The 18REST's psychometric properties are compared to those of the more extended RIASEC item pool and confirmed in a new independent undergraduate sample. Despite differences between genders were found as expected, invariance measurement across gender was indicated. Different ways to use the 18REST in large-scale assessment are discussed.
