This trial will enroll clinics and intervene with clinical staff. We will use vaccination data from children to evaluate intervention effectiveness. We will not enroll children or interact with them directly.

Children's medical records will be eligible to be included in the dataset if children: * are between the ages of 9-12 years at baseline and * are attributed to a participating clinic at 12- or 24-month follow-up. Exclusion Criteria: Clinics are excluded if they: * do not provide HPV vaccine to children ages 9-12 * have a specialty other than pediatrics or family medicine * had an HPV vaccine-specific financial incentive program in the past two years * had a formal HPV vaccine communication training in the past 6 months * had an HPV initiation rate greater than 72$ * had fewer than 49 patients aged 9-12 * had 1 or fewer HPV vaccine providers Children's medical records will not be eligible to be included in the dataset if children: * are not between the ages of 9-12 years at baseline * are not attributed to a participating clinic at 12- or 24-month follow-up
