# Quiz Assignment Overrides
#### A QuizAssignmentOverrideSet object looks like:
```js
// Set of assignment-overridden dates for a quiz.
{
// ID of the quiz those dates are for.
"quiz_id": "1",
// An array of quiz assignment overrides. For students, this array will always
// contain a single item which is the set of dates that apply to that student.
// For teachers and staff, it may contain more.
"due_dates": null,
// An array of all assignment overrides active for the quiz. This is visible
// only to teachers and staff.
"all_dates": null
}
```
#### A QuizAssignmentOverrideSetContainer object looks like:
```js
// Container for set of assignment-overridden dates for a quiz.
{
// The QuizAssignmentOverrideSet
"quiz_assignment_overrides": null
}
```
#### A QuizAssignmentOverride object looks like:
```js
// Set of assignment-overridden dates for a quiz.
{
// ID of the assignment override, unless this is the base construct, in which
// case the 'id' field is omitted.
"id": 1,
// The date after which any quiz submission is considered late.
"due_at": "2014-02-21T06:59:59Z",
// Date when the quiz becomes available for taking.
"unlock_at": null,
// When the quiz will stop being available for taking. A value of null means it
// can always be taken.
"lock_at": "2014-02-21T06:59:59Z",
// Title of the section this assignment override is for, if any.
"title": "Project X",
// If this property is present, it means that dates in this structure are not
// based on an assignment override, but are instead for all students.
"base": true
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://developerdocs.instructure.com/services/canvas/resources/quiz_assignment_overrides.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
