Connector set to enabled but is overriden by the Enable for Connector field. All responses are collected simply as Form Assembly responses (default Enable for Connector is No). Then students are evaluated (based on spreadsheet of replies and the High School essay that will be collected on the portal).
For those students that are accepted, go into their response and edit it, switching Enable for Connector to Yes and filling in the Current School Id field. Then save and reprocess the response. This will create student, parents, Interests/Passions, Extracurriculars, etc. If you do not fill out the Current School Id then the student will not get a primary affiliation connecting them to a school.
Some questions on the form are only for certain ages and are displayed using conditional logic based on the Grade During School Year question.
For parents with more than one kid, give them instructions to use the form a second time. No special processing.
