Educators in the 21st century increasingly argue for the importance of information and communication
technology (ICT) literacy and ask how it can be acquired formally and informally for students’ effective
participation in this highly technology-dependent society. There are, however, insufficient empirical
measures to assess students’ ICT literacy. In this study, a three-factor, 17-item perceived ICT literacy scale
(3F-PICTLS) assessing information literacy (information), internet literacy (communication), and computer
literacy (technology) was developed and validated using a stratified random sample of 826 junior
secondary school students from 36 schools in Hong Kong. Results indicated that the scale demonstrated
good reliability and validity. We discussed the pedagogical and educational contributions of the scale.
