"We acknowledged problems with that program and conducted a thorough review of all of our recent sponsored materials," Scholastic president and CEO Richard Robinson said in a statement issued last week.

In May, amid sharp criticism from several advocacy groups and the editorial board of The New York Times, Scholastic stopped distributing a package of curricular materials on energy issues developed with financial support from the American Coal Foundation. The publishing company also promised to conduct a "thorough review" of its policies and procedures for such sponsored content.

The statement issued last week outlines steps Scholastic is taking as it moves forward.
