This study explores the relationship between grade-level overlap between elementary education (ELED) and early childhood education (ECED) licenses and ECED teacher output. Analysis of Title 2 data indicates that ECED/ELED overlap is extensive, as evidenced by the number of states with grade-level overlaps of 5 (n = 2), 4 (n = 24), 3 (n = 10), and 2 years (n = 7). In the 47 states with both types of credentials, ELED licensees may teach preschool in two states, kindergarten in 30, first grade in 41, second grade in 42, and third grade in 43. The percentage of ECED (relative to ELED) teacher licensure program completers is low in states where elementary licenses begin in preschool (5%), kindergarten (14%), and Grade 1 (23%), but higher in states where elementary licenses begin in Grades 2 (45%), 3 (44%), and 4 (70%).
