^a Retention in program status was defined by whether an LHA conducted at least one educational sessions in the year. Retained LHAs conducted at least one educational session in the past year
^bProgram activity level was defined by the average number of educational sessions completed by LHAs in the year. LHAs considered to be moderately/highly active completed two or more educational sessions in the past year
