The 50 question form has space for 5 digits. For classes that have 6 or more digit ID's you have two options:

**1. Use the 100 question form for all quizzes**:

The 100 question form was developed after receiving feedback on the 50 question form and has space for up to 9 digits. Since ZipGrade will only score questions for which an answer has been defined in the key, you may use the 100 question form for any size up to 100 questions.

**2. Truncate the student ZipGrade ID numbers and store the full number in 'ExternalID':**

Using either just the last 5 or first 5 digits of their ID, store just those digits in the ZipGrade ID field. Have the students use this truncated number when encoding. The ExternalID field is a 'catchall' field that you may store any number/letter string in and is included in any exports. So if you store the full number in that field, you will still have the full number on the exports.

**3. Use a random number and pre-printed answer sheets:**

Either use the truncated ZipGrade ID number as above or let ZipGrade create a random ZipGrade ID. Then print pre-filled answer sheets from the 'classes' tab on the website. These download as a multi-page pdf and have all the answer sheets for the class with the student ZipGrade ID (with darkened circles), name, and class already filled in.
