The Chapel Hill-Carrboro Board of Education sponsored its third annual Summit on Equity and Excellence on Saturday.
The summit addressed the differences in academic performance among ethnic groups.
This year's report's differences in the number of minorities having to re-test on end-of-grade tests and in performance on the Scholastic Aptitude Test are recent signs that have called attention to an achievement gap.
Neil Pedersen, district superintendent, gave a speech Saturday on problems in today's school system and outlined the district's approaches to dealing with them.
Problems included "re-segregation" - a situation in which students socialize only with others of their own race - unequal access to period zero early morning classes and an overabundance of white students in upper-level classes.
"Students can't learn when they're feeling racially isolated," he said.
The district's solutions have included creating equity teams in each school and clustering non-white students into classes together, rather than randomly dispersing them through all available sections of the course.
Many theories exist about the origins of the achievement gap. Pedersen said it is the product of a multitude of factors.
"I think no one really knows the cause of the gap, said Marny Ruben, assistant principal at Seawell Elementary School. "In our school, I think the gap is closing, but I still think we have a lot of work to do."
