The Galbahe Language Tests C1 and C2 measure the Spanish language proficiency of children aged 7 to 8 years (C1) and those aged 10 to 11 years (C2). Equivalent tests E1 and E2 measure the Basque language achievement of the same age groups, respectively. Both tests were designed as part of a study of teaching of the Basque language in parts of Spain to persons of Basque heritage. This manual refers only to the C1 and C2 tests, the Spanish language versions. Each test consists of collectively and individually administered sections. The C1 test, pilot tested with 348 students, contains oral comprehension and expression sections; the C2 test, pilot tested with 333 students, contains oral comprehension and expression measures and Spanish reading and writing tests. Detailed instructions are given for test administration. Standards for grading the tests, which consist of workbook responses to oral or pictorial cues, are defined; and instructions are given for scoring. A profile of students' linguistic achievement and a global score that compares each student with the initial sample are produced. Four pages of tables define performance levels and make comparisons between direct and global scores. The test workbooks and scoring sheets are included. Supplementary handouts are provided. (SLD)
