This study investigated the factors that impact in-service teachers' intention to use technology (n=379), using multiple-indicator, multiple cause (MIMIC)modeling. In this study, in-service teachers' intention to use technology was hypothesized to be impacted by four factors: (1) age, (2) years of teaching service, (3) years of computer use, and (4) hours of daily computer use. Using the structural equation modeling approach, the MIMIC model was found to have a good fit for both the measurement and structural models. Results showed that only years of computer use and daily computer use were significant predictors of in-service teachers' intention to use technology. However, all four indicators (perceived usefulness, perceived ease of use, subjective norm, and facilitating conditions) were significant measures of the intention to use technology.
