3 Predictive validities of the PSU (CTA v Pearson estimates) SOURCE: Pearson, Final Report Evaluation of the Chile PSU, January 2013; CTA

4 Incremental Predictive validities (engineering): (controlling for NEM) SOURCE: S.A. Prado, Estudio de Validez Predictiva de la PSU y Comparacion con el Sistema PAA, Universidad de Chile

5 Content coverage (values from 0% to 100%) It is not fair to expect students to master content to which they have not been exposed. …or, to compare students who have been exposed to students who have not. …how much of the content domain of a test has been taught in the schools.

13 Subgroup differences Differences in test scores among subgroups (e.g., gender, ethnic, school type) should be due only to differences in the attribute measured by the test and not to systematic biases in the test.

19 3. A chronology of mistakes 2000, initial proposal, SIES/PSU project This proposal attempts a redesign of the tests currently used to select students for higher education in Chile. It is expected that [this new test will] have a positive impact in the efficiency of the selection process, improving the psychometric properties of the measuring instruments, and establishing a better articulation between the selection system and the secondary education curriculum.

20 …the Academic Aptitude Test for entry to the university system is under revision, together with the universities belonging to the Council of Rectors. This instrument of entry selection, needs also to be aligned with the new curriculum and may become an exit exam from the secondary education system (World Bank & MINEDUC) SOURCE: World Bank, Implementation Completion Report on a Loan in the Amount of $35 million to the Republic of Chile for Secondary Education, 2001 A chronology of mistakes (cont.)
