Informal teacher-made tests and cross-cultural suggestions are presented as a supplement to a lesson guide for English as second language (ESL) instruction in grades K through 12. The testing ideas are intended as an accompaniment to an activities-based audiolingual language learning program. Following a general discussion of informal language testing, six instruments are described including tests of reading, writing, listening comprehension, language dominance, English production, auditory screening, and oral placement for secondary students. Suggestions are also made for diagnosing oral English deficiencies and constructing an individual education plan. Two illustrated articles on ESL learning activities in elementary and secondary classes are provided along with instructional kits and sample floor plans. (RW)
