Students collecting their A-level results at certain schools in Northamptonshire will be given condoms and Chlamydia tests on results day.
NHS Northamptonshire will be handing out "summer savvy" kits at Wollaston, Guilsborough and Moulton School on Thursday.
The bags also contain an alcohol survival guide showing the dangers of binge drinking and a pair of knickers.
An NHS spokeswoman said they wanted students to be prepared "socially".
"Our advice is enjoy yourself, but know the risks and make positive choices," she added.
Included in the kit is a pair of pants with "I've been tested" printed on them.
The bags are part of a countywide campaign to encourage safer drinking and reduce the number of young people being admitted to accident and emergency.
The campaign has already seen more than 20,000 15 to 24-year-olds taking a Chlamydia test and hundreds have been successfully treated.
