It's something many people have known for a long time - but now it's official - Kapiti Youth Support services works.
After four years hard work, a report called KYS Youth Outcomes and Measures Model, has been released.
KYS manager Rachael Osborne said the model was practice driven by its continual desire for improvement and "questioning how do we know what we're doing works".
"Anecdotally KYS knew it was making a difference to young people's lives, however, we wanted a robust measure that would inform our practice so we could continue to effect change and be relevant to young people."
So KYS partnered with Robyn Bailey and Rae Torrie, from Evaluation Works, as well as others, and the custom built outcome measurements tool was developed.
