Focusing on the experiences of five southern states using teacher testing policies, this survey provides evidence of shared experiences and lessons learned despite the existence of five different sets of certification requirements. The first section of the report concentrates on the national context for the movement toward teacher testing. Conflicting trends in education involving projected teacher shortages and concerns for improved teacher quality and professionalism are identified as some reasons for the current popularity of teacher testing. The second section of the report focuses on the five states: Florida, Georgia, Louisiana, North Carolina, and South Carolina. It highlights why these states decided to change certification requirements, as well as how they implemented new testing programs with what consequences. Specific attention is paid to the impact the different kinds of tests have had on schools of education, the teacher supply, and the local school districts. Repercussions these changes have had on the overall state education system, especially in indicating power shifts in policymaking, are identified. These findings are discussed in terms of their implication for the wider issue of the development of the teaching profession. (Author/JD)
