PurposeTo investigate information literacy (IL) skills of secondary students in Singapore after integration of these skills into school curriculum. The study also explored cyber wellness skills of the students.Design/methodology/approachA survey questionnaire was used to collect data from 14 secondary schools, located in different geographical zones of the country. A total of 3,306 secondary students participated in this survey. A scoring scheme was devised to assess IL skills of the students.FindingsThe students achieved an overall mean score of 52.6%, which is considered as a “middle” level of IL competency. The students obtained high mean scores for two IL skills: “defining information task and analysing information gaps” (60.5%) and cyber wellness (60.1%). Lowest scores were achieved for two IL skills: “selecting information sources” (47.4%) and “appraising the information process and product” (48.0%).Research limitations/implicationsThis study has not investigated IL knowledge of teachers, responsible for teaching IL components. Similarly, content analysis of school textbooks, integrating IL skills, could be useful.Practical implicationsIt appeared that integration of IL skills into school curriculum showed limited success in imparting these skills. This paper suggests measures for improving the integration of IL skills into school curriculum. Findings of this survey will be useful to curriculum planners, education administrators, instructors teaching IL skills and school librarians.Originality/valueThis study was unique as, in addition to standard IL skills, it also investigated cyber wellness skills. It was desirable as now social media have become a popular source for information seeking and sharing.
