Background: We hypothesise that text-messaging and financial incentives would increase tertiary student participation in chlamydia screening.

Methods: A cross-sectional study was conducted over two phases on eight tertiary campuses during 2007. During Phase 1 (6 months) study activities were advertised through student organisations and media.
