While a broad range of tests is available for second language testing, two of the basic approaches are developmental and non-developmental testing. The former is based on psycholinguistic evidence that language development is systematic, with all learners progressing through the same stages. The latter includes content selected in an ad hoc manner, on a linguistic or behavioral basis, with items and techniques chosen largely on the intuitions and experience of the examiner. The Australian Second Language Proficiency Ratings (ASLPR), a rating scale assessing general proficiency, is developmental in structure and is of the type that is most appropriate when the aim of the instruction is to develop practical second language proficiency. While the test, which can be adapted to any language, exists in a basic version for English as a second language and several other languages, development of a version in Indonesian would assist in testing learners of Indonesian as a second language.
