BA Grades - How they are figured

So you've checked Skyward and you see a total of 8 grades listed in skyward for the chapter 6 test.  One says "Raw Score" and other 7 have various codes and descriptors.  Attached is a file that lists the objectives and shows example problems of each.

But what does it all mean?

Let's take Jenny.  She is a student who just took the test.  Mastery Manger, the software that grades the test tells me that she got 20 out of 25 questions correct.  That gives her a raw score of 80% or a B-.  That goes into the system as her Raw Score, or the first grade.

It also tells me that she "mastered" 5 out of the 7 objectives.  So in Skyward, each of those objectives will recieve a 1 or a 2 to show if she has been tested or if she has mastered it.  So her grades on the objectives might look like this:  A E A A A A A E, 5 A's and 2 E's.

This averages out to 71 % or a C.

Because of how the grades are weighted in Skyward, the Objective Grade and the Raw Grade are averaged together equally.  Jenny's achievement on this test would be, overall, a 75% or a solid C.  Not bad but not as good as she hoped.

For the math minded:

The weights on the test are 4.45 for the Raw score (which is actually out of 22 points) and 7.14 for each specific objective (out of 2 points).

So for the raw score, 22 * 4.45 puts it at 99.88 points.
For each objective, 2 * 7.14 = 14.28 each * 7 objectives = 99.96 points.
That makes the test a total of 200 points, equally split between raw and objectives.

What if we aren't happy?

Students can retest to show mastery of those missed objectives by providing evidence of improvement (generally additional practice) and then retaking the exam.  Missed objectives can be made up this way but the raw score does not change.

Why aren't other teachers doing this?

I am personally piloting this system of reporting this year to see if this specific level of feedback is useful or meaningful to students and parents.
