CCLC grantees may attend ONE national training each grant year (as of the 11-12 school year this is no longer required). The training must have prior DESE approval and must pertain to 21st CCLC and/or Afterschool Programming.
DESE will allow up to three people (representing the entire grant/project, not each site) who will be able to take back pertinent information to share with all applicable staff.
You may find a list of national trainings (not all inclusive) here is this portion of the DESE Portal -- the column directly below this one titled "national training calendar".
