Superintendents and representatives of 12 participating school districts met Thursday to begin planning for the potential change to the program, which has allowed more than 60,000 black students in St. Louis to attend suburban schools during the last several decades.
About 4,583 black students from the city transferred last school year, while about 140 white students transferred to city magnet schools.
The Pattonville School District stopped because of its shifting demographics, while the Kirkwood School District began only accepting the siblings of students already enrolled last year because of a lack of classroom space.
A study released by the corporation in 2012 showed transfer students showed little academic advancement in elementary school, but steady improvement in high school in reading and math.
