The revision and process of validation of standards for early childhood special education (ECSE) and early intervention (EI) personnel at the initial and advanced levels of preparation, which occurred during 2005-2008, are described to provide a record of the process and to inform future cycles of standards revision. Central components focus on the importance of the relationships forged in the process, especially with Council for Exceptional Children, and their contributions to its success. The results are discussed in terms of changes in terminology for the ECSE/EI standards, limitations of the process, and suggestions for next revisions. (Contains 1 note and 6 tables.)
