Officials with the Ladue School District and the St. Louis County chapter of the NAACP will meet Friday to discuss recent racial incidents at Ladue Horton Watkins High School.
NAACP board member John Gaskin III told KMOV-TV that the district needs to find a way to get past the incidents.
More than 100 students walked out Wednesday in protest.
On Nov. 10, two days after Republican Donald Trump was elected president, two white students chanting "Trump, Trump, Trump" got on a school bus, with one of them implying blacks needed to get to the back of the bus. The district says the students were disciplined but declined to elaborate.
Students and parents say there have been other incidents.
