This bibliography of 138 works published since 1970 deals with evaluating the acquisition of language skills. The work is appropriate for foreign language instruction and English as a Second Language. The bibliography is divided into four sections: (1) controlled experiments; (2) evaluation in general; (3) evaluation in foreign language learning; and (4) bibliographies on evaluation, including collections of tests. The first section lists works on experiments in second language instruction that have resulted in an evaluation. Part two deals with basic works, particulary those which treat particular aspects and processes of evaluation. The third section is divided into three parts: (1) factors to be evaluated, that is, book, articles and tests on testing the various language skills; (2) testing techniques that have resulted in special studies, namely, dictation, cloze procedure, multiple choice and translation; and (3) works treating current preoccupations and problems, especially self-evaluation and bilingualism.
