What is a DeltaMath test correction?
It is an assignment your teacher creates after a test, and DeltaMath fills it in differently for each student. The help center says corrections “offer extra practice for skills linked to test questions that students answered incorrectly” and “can be generated from either a DeltaMath test or another classroom-based assessment.” On your side it sits in your list like any other work: it “will appear as a normal assignment in your students’ accounts.”
| Linked correction | Unlinked correction | |
|---|---|---|
| The original test | A test created in DeltaMath | A paper test or any assessment “not created in DeltaMath” |
| How your results get in | Retrieved automatically from your test | You enter your test grade and your points for each question |
| Which skills you practice | The test’s skills, or new ones your teacher picks | DeltaMath skills your teacher matches to each question |
| Plan label in the help center | PLUS | INTEGRAL | None shown |
| Your first click | Open Correction, then Initialize Test Corrections | Open Correction, enter your points, then Initialize Test Corrections |
How do you start a linked test correction?
- Open the correction from your assignments and click Open Correction.
- Click Initialize Test Corrections. DeltaMath says your “data from the linked test is used to create an individualized test correction.”
- Read the summary. DeltaMath says students “will then see their grade on the test correction, their new test grade, and which skills and/or videos they are required to practice and watch.”
- Work each listed skill until your high score reaches its target, and watch any assigned videos.
If you open it before you take the test: “If a student has not yet taken the original test, they will receive a notice. If they choose to continue, they will be provided with remediation for all skills on the original test.” Your teacher also decides what replaces a fixed test question. For an Assign THIS Problem, the correction can “randomly assign from the same problem subtype, from the same skill, or assign the same problem again,” so you may see the same problem or a fresh one.
How do you enter your scores on an unlinked test correction?
You type your test grade and one number per question. Your teacher picks which number, and DeltaMath gives these examples:
| Teacher’s setting | You lost points on a question | You got it right |
|---|---|---|
| Points Lost | Lost 1 point on question one: enter “1” | Enter “0” |
| Points Earned | Earned 9 points on question one: enter “9” | Enter “10” in DeltaMath’s example |
The numbers have to agree with your grade: “if students enter information that does not match their total test grade, they will receive a notice to try again.” Once it accepts your entries, you get practice “for each question/skill for which they did not receive full credit.” One question can carry more than one skill.
What does DeltaMath’s Slope Test example show?
DeltaMath walks through a five-question “Slope Test.” Question 1 is Finding the Slope from Points, question 2 is Standard to Slope Intercept Form, questions 3 and 4 share one skill (Graph Line from Slope/Y-Intercept), and question 5 is Slope of Parallel/Perpendicular Lines with only the parallel slope subtype selected. Here is what four students get from the same linked correction:
| Student | Missed on the test | What the correction assigns |
|---|---|---|
| Edgar | Q1, Q2 and Q4 | “additional practice for all three skills he missed” |
| Amelia | Q5 | That skill, restricted to the “Find parallel slope” subtype |
| Gina | Q3 and Q4, both one skill | “the one skill she missed,” with extra practice because she missed two questions |
| Isaac | Nothing | “a message indicating that there are no additional problems for him to solve” |
The correction is organized by skill, so two misses on one skill give you one skill with a higher target. It also keeps the subtype you were tested on, which is why Amelia practices parallel slopes only.
How many problems will a DeltaMath test correction give you?
That depends on two settings your teacher controls, Required and Add. When one skill covers several test questions, “the ‘Add’ setting will allow you to increase the required high score a student must achieve for full credit.” DeltaMath’s example links the skill Linear Equations w/ Distribution to questions 2, 3 and 4, with Required set to 3 and Add set to 2:
| Questions missed on that skill | High score needed on the correction |
|---|---|
| 0 | No practice for this skill |
| 1 | 3 (required) |
| 2 | 3 + 2 = 5 |
| 3 | 3 + 2 + 2 = 7 |
How a high score rises and falls on a DeltaMath skill, including the default penalty for a wrong answer, is covered in our DeltaMath page.
How does credit back raise your DeltaMath test grade?
Your teacher can “allow students to increase their test grade by earning back a percentage of the original points they lost.” “As students work through their test corrections, they will observe their ‘New Test Grade’ increasing.” With credit back at 0%, the New Test Grade line doesn’t appear.
Say you scored 70 out of 100 and credit back is 50%. You lost 30 points, so a finished correction would earn back 15 and show 85. That is our arithmetic from DeltaMath’s description, and its help pages don’t show how partial progress is counted. One more rule: “The credit back percentage is based on the original test grade and not on the late test grade, if points were deducted.” To see what the new test score does to your class grade, try the weighted grade calculator.
Will a test correction assign skills, videos or both?
Your teacher picks one of three options when linking the test:
- Skills only: “Students will receive DeltaMath questions on the skills they missed in their test.”
- Videos only: “Students will be assigned DeltaMath videos corresponding to the skills they missed in their test.”
- Both: “Students will be required to complete both DeltaMath questions and watch DeltaMath videos related to the skills they missed on their test.”
DeltaMath’s Teachers / Schools page says teachers “can assign videos to students and see how much of a video each student has watched.”
Why can’t you see test solutions before your correction?
Your teacher may have turned them off on purpose. DeltaMath tests work differently from assignments: “Unlike assignments, which allow students to work on completion or mastery of skills, DeltaMath tests grade students on accuracy.” On a test, Solutions Shown defaults to Yes, but teachers may choose No to “reuse the same test or have students correct specific questions without solution access.” Results Shown can also be set to After due date, in which case students “only access their grade and review correct/incorrect answers upon reaching the due date.” The correction summary still lists the skills you have to practice.
When should you reset a DeltaMath test correction?
Use the Reset Correction button when your test data changed. DeltaMath says students “should reset their correction if they initialized it before finishing their original test, or if their original test information updates for any reason.” One common update: a teacher can change a score or give partial credit question by question in the test data view. Resetting is safe for finished work, since you “can initialize it again without losing progress on skills previously completed.” If your teacher edits the correction itself, students “may need to re-initialize the correction. However, their prior progress will be saved.”
Do you need DeltaMath PLUS for test corrections?
For linked corrections, yes. The help center labels them PLUS | INTEGRAL, and the test behind them needs a paid plan too: DeltaMath’s Teachers / Schools page lists “Create a test” and “Automated Test Corrections” under DeltaMath PLUS. The free DeltaMath Teacher plan doesn’t list tests, and DeltaMath’s homepage says teachers create tests “with PLUS or INTEGRAL.” INTEGRAL adds LMS integrations such as Canvas, printing to PDF and student work uploads. The help center puts no plan label on unlinked corrections.
PLUS and INTEGRAL are school or district licenses with a “Site dependent price.” DeltaMath’s National List Pricing sheet prices them by a school’s total enrollment in grades 4 to 12:
| Enrollment | PLUS | INTEGRAL |
|---|---|---|
| Up to 750 students | $1,100 | $2,200 |
| 751 to 1,500 | $2,200 | $4,400 |
| 1,501 to 2,250 | $3,600 | $7,200 |
| 2,251 to 3,000 | $5,000 | $10,000 |
| More than 3,000 | $7,500 | $15,000 |
The sheet says this option “only exists with purchase for all enrolled students (in applicable grade levels) in a given school.” Whether you see linked corrections depends on your school’s license.
Where Silent Student fits
We make Silent Student, a Mac and Windows app from El Dorado Ignition LLC that works DeltaMath assignments linked from a Canvas course. It does not take DeltaMath tests. A correction with credit back changes a test grade, so treat it as part of the test and do it yourself. More: Silent Student on DeltaMath.
Questions people ask
Do DeltaMath test corrections raise your test grade?
Only if your teacher set a credit back percentage above 0%. You then earn back that percentage of the points you lost on the original test, and your New Test Grade rises as you work. At 0%, the New Test Grade line does not appear.
What happens on a DeltaMath test correction if you got every question right?
DeltaMath shows a message that there are no additional problems for you to solve. In its Slope Test example, that is what the student with a perfect test sees.
What if you open the test correction before taking the test?
DeltaMath shows a notice. If you continue anyway, you get practice on every skill on the original test. DeltaMath says to reset the correction if you initialized it before finishing the test.
Can you reset a DeltaMath test correction?
Yes. The Reset Correction button lets you initialize the correction again, and DeltaMath says you keep your progress on skills you already completed.
Why does DeltaMath say my test scores don’t match?
On an unlinked correction, the points you enter for each question have to agree with the total test grade you entered. If they don’t, DeltaMath asks you to try again. Check whether your teacher asked for points lost or points earned.
Do you need DeltaMath PLUS for test corrections?
For linked corrections, yes. DeltaMath marks them PLUS and INTEGRAL, and creating a DeltaMath test is a PLUS feature too. Both are school or district licenses, so your school’s license decides what your teacher can assign.
Does Silent Student take DeltaMath tests?
No. It does not take DeltaMath tests, timed skills or proctored tests. A correction with credit back changes a test grade, so do those yourself too.
