Ten national educational leadership associations that make up the National Policy Board for Educational Administration (NPBEA) and 24 state departments of education joined forces in 1994 to put together a knowledge base, performance standards, and professional dispositions for administrators. The result was a publication by the Council of Chief State School Officers (CCSSO, 1996) entitled, "Interstate School Leaders Licensure Consortium (ISLLC) Standards for School Leaders." The ISLLC standards for school leaders represent the best practice of representatives from K-12 schools, districts, universities, and professional associations at both the state and national levels. They define the responsibilities of effective school leadership in 21st century schools. There has been little research on leadership preparation programs generally and only modest attempts have been made to assess students' perceptions of their coursework. Likewise, there has been little research on the impact of the standards and dispositions. If ISLLC has had an impact on the field, it is assumed that the curriculum of educational administration programs would have changed and that administrators taught in these programs would view the standards and dispositions as important to their practice. This study was designed to determine the importance of the six ISLLC standards generally and the 42 dispositions specifically. In addition, it examined the extent to which the ISLLC standards and dispositions were emphasized in preparation programs. Given the increasing participation of women in administration, this study also tested for gender effects in the administrators' perceptions. (Contains 3 tables.)
