 Students were provided with a very limited selection of sources, including material from a known Holocaust denial website, but were not allowed access to the internet or other materials that show that this material had been discredited.A follow-up investigation by "The San Bernardino Sun" found that (contrary to the district's initial claims) at least 50 of the 2,000 students taking the test ended up concluding that the Holocaust did not occur.The district has apologized and promised not to repeat the exercise, and also sent all the eighth graders to visit the Museum of Tolerance in Los Angeles, a museum known for its exhibits about the Holocaust.
