The International Computer and Information Literacy Study (ICILS) is a computer-based international assessment of eighth-grade students' computer and information literacy (CIL) skills—that is, the "ability to use computers to investigate, create, and communicate in order to participate effectively at home, at school, in the workplace, and in society" (Fraillon, Schulz, and Ainley 2013). ICILS is sponsored by the International Association for the Evaluation of Educational Achievement (IEA) and conducted in the United States by the National Center for Education Statistics (NCES). This study will allow the U.S. to begin monitoring U.S. student skills and experience using technology compared to that of other nations and to provide data on factors that may influence student computer and information literacy skills. In addition, many international assessments, such as the Trends in International Mathematics and Science Study (TIMSS) are transitioning from a paper-based format to a technology-based format. In order to support these transitions, the data collected through ICILS will provide valuable information with which to understand the nature and extent of the "digital divide" and has the potential to inform understanding of the relationship between technology skills and experience and student performance in other core subject areas.

ICILS reports on (1) students' abilities to collect, manage, evaluate, and share digital information, and (2) students' understanding of issues related to the safe and responsible use of electronic information. In addition, student, teacher, school, and national context questionnaires collect information on (1) the policies, curriculum, resources, and practices related to CIL education across countries, (2) students' use of computer technologies in and out of school, and (3) the use of information and communication technologies (ICT) in teaching.

The first administration of ICILS was conducted in 2013, and 21 education systems around the world participated. The United States will participate in ICILS for the first time in 2018.
