It is possible to regrade a test after it has taken place through the Blackboard interface. This is particularly useful if the answer key for a question was set incorrectly, or if a question needs to be withdrawn.We recommend creating a backup of the course first:
Click Packages and Utilities, Export and Archive and wait until you get an email from the system to tell you it is ready. If you did need to get the original data, ISS could help you using the backup.
To regrade the questions, identify the question that needs to be amended in the test canvas. When you make the amendment you will be given the option to “submit and update attempts” – choosing this option will automatically re-grade all of the attempts in light of this amendment.
It is possible to manually regrade a question for each student. This is particularly useful if you have used text entry questions (e.g. fill in the blank). For fill in the blank questions, you may just want to focus on the students who have submitted answers that are marked as incorrect and think about updating the test for the following year to account for different spellings etc.The 2013/2014 version will have wildcard features to make things easier.
To regrade a question:
Go to the module/organisation in Blackboard and click Grade Centre, then Full Grade Centre under Control Panel.
Find the column for your exam/test. You may need to scroll to the right to find it.
Use the drop down menu on the Column Header for your exam to access the Grade Questions feature.
You will see a list of the questions. Click the response number on the right hand side to start grading that question.
You can choose to regrade anonymously by ticking the box at the top left. Click Edit next to any given answer to make the change.
Click ‘Grade Centre’ in the Control Panel (bottom left of the screen).
Scroll to the right until you see the column for the exam. You can hover over the column headers to see the test’s full name.
Scroll down to see individual student scores.
Click a cell and choose View attempts to see an individual student’s answers.
To save the scores to a spreadsheet (CSV file)
From the Grade Centre, click Work offline (near top right) and then Download.
Choose selected column and then find the column for the exam form the drop-down list.
Where it says delimiter type, choose Comma.
Scroll down and click Submit.
There are a number of reports built into Blackboard. Some do not work for exams with randomised question sets.
This report is helpful to check immediately after the exam to ensure the questions and answer key were correct. To see the Attempts report:
Click the column header and then click the downward pointing arrow to bring up the drop down menu.
Click Attempt statistics.
Please note, this report may take a while to process.
The report will appear onscreen. Scroll down to see each questions, and the percentage of students that choose each answer. If you find that a large number of students have chosen the wrong answer, you might want to check the question is correct. It is possible to re-score a question or test. Get in touch with OLAF Admin if you need to do this.
Click the column header and then click the downward pointing arrow to bring up the drop down menu
Click Column statistics.
This will display score distributions and averages.
Setting the column to display a percentage instead of a raw score
Click the column header and then click the downward pointing arrow to bring up the drop down menu.
Click Edit Columnsettings.
Change the primary display to percentage.
You can also change the secondary display to score if you want to see both. The secondary display appears in brackets.
Sometimes it is appropriate to show students the results of their test, and possibly even feedback on each question, through Blackboard. If using this, please inform students whether the mark is final or provisional. We recommend viewing the Attempt Statistics report where possible to ensure the test looks correct.
Note: Whichever method you use, students will only see their own scores/feedback.
To reveal/hide the score in Grade Centre:
1. Log into the course.
2. Under Control Panel, click Grade Centre, then Full Grade Centre.
3. Scroll to the right to find the column for your test. Hover over the headers to see the full name.

We often get queries about whether it’s possible to amend or delete questions from a test in Blackboard when the test has already taken place. The answer is yes – and if the test uses question types that have automatic grading Blackboard will automatically regrade the test to reflect the changes you make.
That said, there is a bug in Blackboard which on rare occasions can cause problems with students’ test attempts when you amend or delete a question. To help safeguard against this we recommend that you take the steps below before you make any changes to a test after it has taken place.
Close the test and make sure that there are no attempts in progress
Ensure that the test is no longer available to students, so that there is no danger that they might be taking the test when you make the change. To check this:
Go to the Content Area where the test is deployed in the module, and hover over the name of the test. Click on the dropdown arrow that appears, and select Edit test options:
EITHER under Test Availability make sure that for Make the link available the No option is selected:
OR/AND scroll down to the Display Until date, and make sure this is set to a date and time in the past (this can be 5 minutes from the current time):
Scroll to the bottom of the test options screen and click Submit to save any changes you have made.
Open the Grade Centre by clicking on Control Panel > Grade Centre > Full Grade Centre.
Find the column for the test, and scroll down to check whether there are any attempts in progress, shown with the ‘Attempt in progress’ icon of a blue clock:
In the module, open the Full Grade Centre. In menu bar at the top of the screen you’ll see the option Work Offline on the right hand side. Click the down arrow and select Download:
In the Download Grades screen leave the default options selected, and click Submit.
On the next screen click the Download button and save the file to an appropriate location (e.g. your H: drive or shared file space for your school).
Download test results
In the Grade Centre find the column for the test, and click the dropdown arrow to the right of the column name. Select Download Results from the menu:
In the Download Results screen leave the default options selected. Click the button to download results, and again save to an appropriate location.
Note: both of these actions produce a .csv file, which you can open and amend in Excel as required.
Amend or delete a test question and regrade attempts
Once you have completed the steps above you can go ahead and make the required changes to the test.
Open the test canvas. You can do this via the Control Panel > Tests, Surveys and Pools > Tests, then hover over the name of the exam and click the dropdown arrow. Select the Edit Test option.
Scroll to the question that you need to amend or delete, and hover over the title. Click the dropdown arrow that appears:
To amend a question select Edit from the dropdown menu. Make the required changes. Click Submit and Update Attempts. Blackboard will display a warning message; click OK, and the test will automatically be regraded:
To delete a question select Delete and Regrade from the dropdown menu. Blackboard will display a warning message. Click OK, and the test will automatically be regraded:
Once you have amended or deleted all of the required questions, check the Grade Centre column for the test to ensure that the attempts have been automatically graded as expected.
In following years, it is much more efficient and effective to work from the questions that were tested online by students in exams, than to get a Word version converted from scratch again. The conversion process, particularly if you have not followed the suggested format, can introduce errors.
Tag and use last year’s questions.
Copy and amend last year’s test.
Ask us to produce an editable version of last year’s test that will convert more easily.
After you have run a Blackboard test or an OLAF exam that is automatically marked, the students’ grades appear in the grade centre as soon as they press the ‘Save and Submit’ button at the end of the test. If a student forgets to press the button, instead of their grade in the grade centre you will see an ‘attempt in progress’ icon of a blue clock. An example of this is shown below:
To override this you can submit the attempt on behalf of the student.
To submit a test attempt on behalf of a student:
1. Hover your mouse over the grade centre cell with the attempt in progress icon, and click on the dropdown arrow. Click on ‘Attempt’, as shown below:
2. The student’s attempt will open. Click on the arrow at the right of the ‘Test Information’ bar to expand it.
3. The Status will show ‘In Progress’. Click on the ‘Submit Attempt’ button, circled in the example below:
4. A popup will appear asking you to confirm that you want to submit the attempt on behalf of the student. Click OK.
5. The Status will now show ‘Completed’. Either click ‘Exit’ to return to the grade centre, or use the left and right arrows on either side of the student’s name near the top of the screen to scroll to the next student’s attempt.
Immediately after an exam to highlight questions that need checking for errors
Before updating the exam for the following year to check for errors and assess how difficult your questions are and how well individual questions discriminate between high and low performers
To run an item analysis report:
Go to the module and the Grade Centre (‘Tests‘ or ‘Full Grade Centre’).
Find the column relating to your exam/test
Click the column header and access the drop down menu to find ‘Item Analysis‘
Select the test and click Run. It may take a while depending on the complexity of the exam, numbers of examinees and the load on the system. You will see a message telling you that the report is running. You can check back later.
When the analysis has run, you will be able to select it from the list.
Interpreting the report
A summary at the top of the page shows you how many questions are good discriminators (distinguish between low and high scoring students on the test overall). It also shows you the number of Easy, Medium and Hard questions.
Further down, you can see Discrimination and Difficulty scores for the individual questions. It also indicates questions that may need to be reviewed. See the key on the page.
Questions marked with a red dot have poor discrimination scores and/or easy or hard difficulty values. Click the blue question text to get more info on that individual question.
A higher discrimination score number suggests a question is a good discriminator. A low or negative score is a poor discriminator
The higher the difficulty score, the ‘easier’ the question was for the students taking the test
Click Edit Test to make a change to the question. If you change the correct answer, you can then ‘Re score’ the test. This will make the change for future tests as well. See also the video guide from Blackboard on Demand
