Distinguish Required Data Entry Fields

The Department of Transportation (DOT) and Operating Administration websites distinguish clearly and consistently between required and optional data entry fields. Users should be able to easily determine which data entry fields are required and which are optional.  One of the following approaches is used to distinguish required data entry fields:

• An asterisk is provided in front of the label for required fields.  In addition, text is provided stating: “A field with an asterisk (*) before it is a required field.”  This statement must precede the beginning of the data entry form.
• the word “(Required)” is provided in front of the label for required fields. In addition, text is provided stating: “All required fields have the word (Required) in front of a label.”  This statement must precede the beginning of the data entry form.
• Fields are separated into required and optional when practical.  These groupings must be clearly labeled “Required” and “Optional” and include the statement: “Fields are organized into required and optional groupings.”
