The purpose of the study was explained to them and each was asked to provide a letter of recom mendation to their membership encouraging them to assist with the study by completing and returning the questionnaire. Specific letters of en dorsement from these respective professional organizations were then in cluded with the mailing of each questionnaire (Appendix B). Much of the material for the review of literature was obtained through the Educational Resources Information Center (ERIC) and the Iowa Network For Obtaining Resource Materials For Schools (INFORMS). Related dissertations from the Iowa State University library proved to be valu able resource material, as well. The survey instrument (Appendix A) used in this study was developed with the assistance of Richard P. Manatt, Professor of Education at Iowa State University and graduate students in one of his administration classes. The instrument was field tested through a pilot study under the supervision of Anton J. Netusil, Professor of Education at Iowa State University. The survey was administered to a randomly selected sample via the U.S. mail. *
