The READ (Reading Evaluation--Adult Diagnosis) test, developed to provide the information needed by teachers of reading for adults or for older students who need more mature materials, is provided. The test is divided into three parts. Part I tests the student's acquaintance with words in general. This part is composed of four lists derived from words that appear both on the Botel Reading Inventory Tests and on The Functional Reading Word List for Adults. From this test's results, the teacher can determine what words the student can read of those he is likely to encounter most frequently. Part II is a series of tests that provide an index of the student's word recognition skills. This part begins with tests of reading subskills such as knowledge of the letters of the alphabet and knowledge of the sounds that letters represent. The other tests indicate whether the student knows the most common pronunciation of groups of letters that occur frequently in English. From the results of Part II, the teacher knows whether the student has the information he needs to determine independently the pronunciation of a word. Part III provides the teacher with the general level of the student's functioning when he is using materials in context. It also provides an indication of the student's reading comprehension. Part III is composed of stories whose themes were suggested by the experience stories of adults in basic reading instruction. The READ test battery is to be administered individually. A test summary sheet for test results is provided. Also included in this book is a Group Screening Test, which can be used to determine which students need further testing and diagnosis. (DB)
