The purpose of this research was to know whether there was influence of PECS (Picture Exchange communication System) method toward non-verbal communication to autism children in YP PG/TK Puri Mutiara Bunda Sidoarjo or not. The method of this research used was quantitative pre experiment kind. The design used one group pre-test post-test with 6 subjects of autism children.

The research result was proven that non-verbal communication ability using PECS (Picture Exchange communication System) method was obtained ZH value = 2,05. Because ZH value was 2,05 (above / greater than 1,96) so it could be concluded that Ho (Null hypothesis) was refused and Ha (Work hypothesis) was accepted. If Ha was accepted it meant there was influence of using PECS (Picture Exchange communication System) method toward non-verbal communication ability to autism children in YP PG/TK Puri Mutiara Bunda Sidoarjo.
