Student quiz score through an API call

Question

Hi everyone,

Does anyone know the way to get student's quiz score through an API call using student's ID?

It looks like there is a way to get the students who answered certain questions correctly for a specific quiz, but I'm having trouble finding the right API function to get specific student's quiz score.

Thank you in advance

I'm not sure what you mean when you say "it" returned a 2d array of titles and undefined. There was a lot of different advice given in the posts and I'm not sure what exactly you're trying.

To double check, are you using classic quizzes (new quizzes doesn't have the API functionality yet), and are they graded quizzes (as opposed to practice quiz or ungraded survey)?

@kj460 ,

In addition to what  @bneporadny  wrote, you may be able to use the List submissions for multiple assignments endpoint of the Submissions API. You'll need to know the corresponding assignment ID for the quiz to do this. It's what the gradebook uses to download grades and is the API version of what he's getting through the student submissions report.

What I do is get the Quiz Submissions like he mentioned, then iterate through them. I was doing an analysis where I needed the grade for all of the students and for of the attempts, not just the last one. If submission.attempt > 1, then the student has multiple attempts. You can fetch the quiz submission for each attempt by adding an id and attempt to the quiz submissions call.

Out of curiosity, which call are you using to see which students got certain questions correct? I haven't been able to find a reliable way to extract student answers from Canvas, either through the API or through Canvas Data. The closest I've been able to come is with the Quiz Audit Log, so if you've found a way, I would love to know it.

Hi Kevin ,

I haven't used the quiz API's to pull quiz data for individual students so I can't help you there (maybe someone else can in the Canvas Developers‌ group). But I can tell you how I do this for my school.

On a daily basis I call the student submisisons‌ report and store that in a local database table and from there I am able to produce reports showing what students got on what quizzes/assignments.

I did find one way to do this and that is to pull every submission for a particular quiz and then parse through the json‌ response looking for the particular students you're looking to get the quiz score on. This can be done by using the Get The Quiz Submission api‌ (Canvas LMS REST API Documentation )
