While the standard Archer Application Builder supports a wide array of field types, the Questionnaire module uses a more specialized subset of fields within the Question Library . According to the Questionnaires and Assessment Maintenance curriculum, questions are designed to gather specific response data that can be scored.

Valid question types include Values List (for multiple choice), Date (for timestamped responses), Numeric (for quantitative data), and Text (for qualitative comments). The User/Groups List is also a valid question type, often used to identify stakeholders or owners during an assessment. However, an Attachment is not a standalone question type in the library. In Archer Questionnaires, attachments are typically handled as "supporting evidence" linked to a specific question or the record as a whole, but you cannot define a question as an "Attachment type" in the same way you define a "Values List" question.
