New Turnitin LTI Issues

Goal: This discussion is to highlight the issues experienced while implementing the new Turnitin LTI.

I hope this discussion will help other admin implement this tool with a full understanding of it's limitations and functionality. We are a fully online school and implemented this tool without testing (our first mistake). We use a course copy model to create every course. Our LTI settings are copied over (without dates) from our master courses.

Overview of our Pain Points:

  • Multiple dates (start date, due date, feedback release date)
  • Resubmitting assignments
  • Assignment parameters
  • Rubrics
  • Submit Button
  • Additional options
  • Already submitted work

Multiple Dates

We have found multiple issues/errors that happen due to dates. An assignment has 3 different slots for dates: start date, due date, and feedback release date. We've found that:

  • The due date can not be the same as the feedback release date. This will generate an error and the behavior will not allow the student to submit work. Our workaround: We went in to every assignment and adjusted the feedback release date to be 2 days after the due date. Note: the due date can not be change from the TII settings- this must be adjusted on the assignment.
  • The start date is created when you enable the LTI on an assignment. The start date must be before the due date.

Resubmitting Assignments:

The TII LTI will allow assignments to be resubmitted up until the due date. However, this must be enabled on the assignment. Students are no longer able to resubmit work after the due dateNote: once a student resubmits work, the original work and teacher comments will be lost in the Feedback Studio.

Assignment Parameters:

We found multiple errors caused by our preexisting assignments. This will generate an error and the behavior will not allow the student to submit work. Assignment parameters:

  • Assignment title were too long- the max is 99 characters
  • Assignment title using a ; (this might have been resolved recently)
  • Assignment point values were not a whole number
  • Assignment due dates matched the feedback release date (see multiple dates above)


Assignments with the TII LTI enabled, the rubric is "replaced" with the TII LTI. Resulting in the rubric appearing as "not on the assignment." However, in Speedgrader the rubric is still attached to the assignment.

Submit Button

The location of the button is somewhat hidden to students when the LTI is enabled. Traditionally, the button is in the top right corner, which they grow accustom to. However, the LTI moves the button to the lower portion of the screen and is within an iframe. And depending on the device or browser, the student also has to scroll within the iframe to find the button.

Additional Options

Be sure to review the additional options carefully. We have dozens of assignments in one course, which makes any adjustment very time consuming. Options to consider: accept various file types, etc.

Already Submitted Work

If students have already submitted work and you enable the LTI after, all of the already submitted work will be lost.

Please feel free to add to this discussion so we can all help each other during this transition.

Thank you,

Can you let me know the pros and cons of using a Canvas rubric versus the TII rubric for TII assignments? Best practices?

We currently use Canvas rubric "behind the TII curtain" and then include a screen shot of the Canvas rubric in the Canvas assignment instructions (and/or a PDF of the rubric) since Ss need to be able to see it up front when accessing their assignment instructions.

Keeping in mind that there is a triumvirate of partnering software - TII, SpeedGrader and GradeBook - we have strongly recommended that our faculty use TII directly to score and give feedback on student work (too many problems with SpeedGrader to/from Grade Book and SpeedGrader to/from TII). However, we have found that still using a Canvas rubric creates double work for Ts: then they have to score and give feedback in TII, then go to SpeedGrader and score the rubric itself. Thoughts?

Our teachers are doing their grading in TII so they are mostly using the rubric there.  Some scan a copy and attach as a document to the assignment.  The main thing they like about the TII grader is the saved comments that they can reuse.  If they had that feature, more would grade in speedgrader and not in TII.

How do you all handle situations where faculty may want to allow a student to resubmit AFTER the due date is past? If one uses the creation of a new assignment as a workaround, what then happens in Gradebook? How might grade weighting be affected? Or, can a teacher simply delete the student’s first submitted paper and then resubmit/re-upload the revised one (if they receive it via email) for the student once the due date is past?

This is hard to test without possibly messing up an assignment in a live course.

Thanks for all ideas.


Hi - we have a similar scenario where we are having to use additional assignments for extensions, and we are putting an EX in the gradebook for the assignment which is not being used for that student. For 2nd attempts (where there is a mark in both, but only one should count towards total grade) we use the rule to exclude the lowest grade within that assignment group. Hope that helps! 

Some of our staff prefer the Tii rubric as it is non scoring. We also have issues with the Canvas rubric for complex marking grids as it seems to 'break' above a certain complexity. However we are having to warn staff about the Tii rubric as if any assignment settings are changed once marking has started (eg feedback release date) the rubric marking is lost with no way to retrieve it, and no warning. I had a member of staff lose marking on 100 assignments the other day! This has been reported to the Tii engineers but has been with them for a while now. Big risk for us currently unfortunately.

Thanks. This is very helpful. Can you tell me more about what you mean by non-scoring?


Hi - yes of course. The Canvas rubrics force you to allocate a score against each criteria, which may then give a different total score to the overall grade given to the assignment, which causes confusion for students. Most of our lecturers prefer to give an indication of grading range against criteria within the rubric, with comments, but just give one overall grade rather than a calculated score. They can do this in Tii. I know some people have put in a workaround to just make the rubric score total 5, whereas the overall grade is a %, but this still causes confusion.  The 'non-scoring' rubric has been identified by the UK HEI user group as a top 5 priority requirement, but my understanding is that this development is not currently scheduled. Staff therefore prefer to use the Tii rubric at the moment, but we do have this risk with the settings change issue! 

The other rubric issue identified by the UK group was to do with the alignment breaking once you get to a certain number of criteria/bandings, and issues with the colours used in the Canvas rubrics not being compliant with accessibility requirements. Hope that helps!

The API still works, so as long as it's still working, I would not use the LTI tool for groups and just set it up like normal.

We have both the API and the LTI enabled. You can do a gradual shift to LTI if you'd like. All API stuff still works and is there.

We use the Canvas grading rubric because we have to keep track of who grades. Turnitin doesn't send back the name of the grader, so we aren't able to use it as a grading tool. I have talked with their eingineers about this, and they have stated that they don't have a field that collects the user's Canvas ID or SIS ID or anything like that, so it's not possible for them to do a passback of who graded even if they wanted to. (I hope they change this!)

  1. That said, before changing  submission to LTI, we  create the rubric in Canvas. 
  2. Then, we copy the rubric (paste it in word and remove extra "garbage" from the copy), then paste and format it in the assignment submission directions. 
  3. Then we attach the external LTI tool. 

This way the student is able to see the rubric since the LTI obscures the Canvas rubric from view. 

Grading is exactly the same and doesn't change anything. However, note that sometimes Turnitin fails to sync the assignment back to Canvas and so the assignment is in the Turnitin assignment window but not synced back to Canvas in speedgrader. When this happens, just create a ticket to tier 1 and they now (finally thank goodness) have th ability to sync the student's work back to Canvas when the sync fails. 

Know that You should remind students not to resubmit quickly in a row; Turnitin has a bug where if they submit quickly, the submissions have a fatal error where they get off permanently, so they submit file 1 and it gets lost; they submit file 2 and it is submitted to canvas as file 1 (it's pretty bad.) I have submitted this error but haven't heard back about if they are working on fixing this or not. Howeve,r this is something to be aware of and we post this information in our submissions so students are aware of how they need to subimt.
