 Kaczynski attended grades one through eight in Evergreen Park District 124 Schools . As a result of testing conducted in the fifth grade , which determined he had an IQ of 167 , he was allowed to skip the sixth grade and enroll in the seventh grade . Kaczynski described this as a pivotal event in his life . He recalled not fitting in with the older children and being subjected to their bullying . As a child , Kaczynski had a fear of people and buildings , and played beside other children rather than interacting with them . His mother was so worried by his poor social development that she considered entering him in a study for autistic children led by Bruno Bettelheim .
