Laboratory assistants in biology and medicine play a central role in the operation of laboratories in hospitals, research institutes, and industries. In this article, we present a paper-and-pencil test, measuring the professional knowledge of prospective laboratory assistants (acronym: PROKLAS) about laboratory tasks in biochemistry and cell biology. The developed items cover three categories of laboratory tasks: responsible action, data management, and laboratory techniques. A sample of N = 284 Vocational Education and Training (VET) students (average age = 20.0 years [SD = 3.3]) were tested in a cross-sectional study. The sample comprised of prospective biology laboratory assistants, biological technicians, and medical laboratory technicians.
Confirmatory factor analysis (CFA) indicates that the test allows us to measure
knowledge of biochemistry and cell biology as two empirically separable constructs. Moreover, CFA with covariates widely confirms the validity of the respective subscales. In general our analyses indicate that PROKLAS can be effectively and successfully used for summative and formative VET evaluation.
