SALGADO, Jesús F. Predictive validity and equal treatment of "Competition" as a selection method for State Treasury inspectors and treasury technicians. Rev. psicol. trab. organ. [online]. 2023, vol.39, n.2, pp.109-119.  Epub Nov 13, 2023. ISSN 2174-0534.

The "competition” (“oposición” in Spanish) is the method of personnel selection for the higher Corps of the Spanish civil service, and hundreds of thousands of candidates participate in the competitive examinations each year. Despite this, its predictive validity and its potential effects on equal treatment for men and women remain unknown. This article presents two independent studies devoted to establishing the predictive validity and the degree of equal treatment of the "competition". In the first one, the validity was examined with candidates for the Corps of Treasury Technicians. The results indicated an operational validity ρ = .54 (N = 392) and an average Cohen's d value of .14 for equal treatment favorable to men. The second study was conducted with candidates for the Corps of Senior Treasury Inspectorate and the operational validity was ρ = .50 (N =.70) and Cohen's d of .33 favorable to women. The results indicate that the "competition" shows similar or superior validity to that of the best personnel selection instruments. Finally, implications for practice are discussed and recommendations are made to improve this system of access to the civil service.
