This study examined grade level and gender difference with respect to elementary students' science and technology self-efficacy. Additionally, relationship between socio-economic status (SES) and self-efficacy was examined. A total of 145 elementary students participated in the study. Self efficacy towards Science and Technology Scale was used to collect the data. While results showed that there was no significant difference across grade level and gender, positive relationships were found between number of books in home, frequency of buying a daily newspaper, and income as indicators of SES and self-efficacy.
