This paper presents a critique of the Northwest Regional Educational Laboratory's (N.W.R.E.L.) review of the Mat-Sea-Cal Oral Proficiency Tests in their publication, Oral Language Tests for Bilingual Students. That publication was released in July, 1976 as a guide to administrators and program coordinators in the selection of instruments for assessing students' language dominance and oral proficiency (-ies). In rating each instrument, four criteria were explored: measurement validity, examinee appropriateness, technical excellence, and administrative usability. Several questions within each criteria were examined in determining the overall criteria rating. A descriptive review of the Mat-Sea-Cal is presented and the reviewer's rating is summarized in a chart. This critique scrutinizes the evaluations rendered to the Mat-Sea-Cal by the reviewers in each of the four criteria. Discussion is offered on several points. Differences in perception between the author and the N.W.R.E.L. reviewers on the evaluation of the Mat-Sea-Cal are enumerated. (Author/CFM)
