The purposes of this study were to determine if cloze tests would yield reading instruction levels identical to those obtained with an Informal Reading Inventory (IRI) and if there would be discrepancies in the reading levels yielded by the two instruments for subjects from a lower socioeconomic level. The investigator, with the assistance of one reading specialist, administered an IRI and cloze tests to 122 sixth grade students from an upper middle class socioeconomic level and 95 sixth grade students from a lower socioeconomic level. The data were placed in a two way contingency table and subjected to chi square analysis to determine if a statistically significant relationship existed between the reading instructional levels obtained through the use of cloze tests and the IRI. The results indicated that only twenty-nine percent of the individual subjects were assigned the same reading instructional level by the two instruments. Also, cloze tests yielded depressed reading instructional levels for students from a lower socioeconomic level and are inappropriate for use with these students. (Author/WR)
