This monograph was developed to provide elementary classroom teachers with suggestions for diagnosing several aspects of children's reading abilities and attitudes. The techniques described adhere to diagnostic guidelines set forth in the first part of the monograph and should be useful in regular classroom situations. The remainder of the monograph is organized around the types of questions that teachers typically have about their students as readers: (1) Where should this child be placed for reading instruction? (2) What are this child's strengths and weaknesses as a beginning reader, in terms of general reading ability, and as a content area reader? and (3) What are this child's perceptions of the reading process and attitudes about and interests in reading? A diagnostic strategy or technique that may be helpful in answering each question is provided in the monograph. Eight figures of data and varied information are included; 24 references, and appendixes containing titles and grade level designations for basal reading series, a written language evaluation form, analysis of miscues, and holistic reading assessment forms are attached.
