Why I Switched Grading Practices—and Why I Call It “Skill-Based Grading”

 

Why I Switched Grading Practices—and Why I Call It “Skill-Based Grading”

When I set out to grade more equitably, I ditched the traditional curriculum map and rewrote everything around standards. That sounded good…until I tried to explain it to students and parents. “Standards Based Grading” felt abstract and overwhelming.

So I rebranded it Skill-Based Grading. A skill is tangible. One standard can hide several distinct skills, and each needs its own entry in the gradebook. Example:

Common Core StandardSkills I Grade Separately
G-SRT.6 Write a trig ratio1 idea


G-SRT.7 Show sin & cos are complementary		1 idea
G-SRT.8 Solve right-triangle problems                    
3 ideas
    • solve for an angle
    • solve for a side
    • use the Pythagorean Theorem in context

Breaking standards into bite-sized skills lets struggling students see exactly what they’re working on, track progress over time, and even search YouTube for the missing concept.

The 4-Point Scale Students Use to Self-Assess

I ask students to mark their own work as None / Some / Most / All, which translates to:

Self-RatingMeaningPoints in Gradebook
1 – Little to no understanding        0-40 % mastered        4/10
2 – Some understanding        < 50 % mastered            6/10
3 – Most understanding        > 50 % mastered            8/10
4 – All problems correct        Complete mastery        10/10

After they self-score, I add a “+” ( +10 %) or “–” ( –10 %) to calibrate where they were a bit hard—or easy—on themselves. That ±20 % teacher variance keeps grading fair across the class.

Building the 3-Column Assessment

Each concept appears in three column side-by-side boxes on every quiz:

Column    What Students SeePurpose
Level 2 (Left)    Vocabulary & prerequisite skills    “Just-in-time remediation”
Level 3 (Middle)    Core computation problem    Meets the high-school standard
Level 4 (Right)    Word-problem application    Extends the skill in context

Trig example (Skill: solve for a missing side)
Level 2: Label opposite/adjacent/hypotenuse and write the correct ratio.
Level 3: Solve for a side in a problem with a diagram.
Level 4: Angle-of-depression airplane application problem—draw, model, solve.

How students tackle it

  • Honors students work right → left: finish the Level 4 column first, then Level 3, and (if time) Level 2.

  • Students building from a low baseline work left → right so I can pinpoint exactly where they are on the learning progression.

What “Evidence of Understanding” Looks Like

I’m not hunting perfect arithmetic; I’m hunting thinking.

  • If a student writes “SOHCAHTOA” in the Level 2 box, that shows Level 2 understanding.

  • In a substitution problem, simply replacing the variable with the given expression counts as partial understanding—even if the algebra isn’t finished yet.

Recognizing and rewarding progress (not just perfection) builds confidence—critical for students who have struggled in math.

Retakes, Spiraling, and the Growth Score

Students redo 1–3 problems per concept multiple times per term. New evidence can replace the old score or add a separate growth score—your choice. Either way, improvement matters.

Using NWEA MAP Data as the “Final”

We already test like crazy in a Title I school, so instead of a massive semester final I use our district NWEA data:

  • Four strand scores (Algebra, Number Sense, Geometry, Probability & Statistics)

  • 10-point growth = roughly one grade level jump

I record strand data competency and growth, for the current class. For example Statistics and Geometry strand data for first semester geometry. I also grade and or recore overall compentency and growth for all 4 strands, but only if it helps a student’s course grade—never to punish.

Early Wins Matter: Statistics Before Geometry

Most of our non-accelerated students (many are Heritage Spanish speakers) take Geometry before Algebra 1. We start the year with Statistics—visual, discussion-rich, and low on prerequisite computation (scatterplots, correlation vs. causation, measures of center).

Early success lets me celebrate like they’ve won the Super Bowl, then we slowly layer in Geometry vocabulary—infusing and explicitly teaching those new terms in the Level 2 boxes—so language never becomes an invisible fence.

Takeaways

  1. Rename the game. “Skill-based” sells better than “standards-based.”

  2. Expose the hidden skills. One standard can equal three separate gradebook entries.

  3. Let students score themselves first. None / Some / Most / All + your ±10 % keeps things honest.

  4. Differentiate in one sheet of paper. The 3-column quiz meets every learner where they are.

  5. Measure growth—and honor it loudly. Whether through retakes or MAP data, show kids that improvement counts.

When students know what they’re missing and believe every step forward earns credit, they lean in—asking smarter questions, searching for tutorials, and owning their learning. That’s the heart of growth-based grading.

The Biggest Problem in Mathematics Education Today!

  The Hidden Barrier to Math Success: Confronting Learned Helplessness in Our Classrooms As a math educator with over 20 years of experience and more than 2,500 students passing through my classroom, I’ve seen the education system from many angles. I’ve taught in affluent and underserved schools, engaged with parents, collaborated with educators, and debated with college professors about what works and what doesn’t in education. One common thread runs through all these interactions: the urgent need to address why so many students struggle with math and, more importantly, what can be done about it. Lately, I’ve had more meetings with parents frustrated that their child is struggling with math, convinced the issue lies with my teaching. But as someone who has worked to refine my curriculum, instruction, and scaffolding strategies, I have to ask: What’s really going on here? The truth is sobering. It’s not just the curriculum, standards, or even the instruction. It’s learned helplessn...

Lessons From the Other Side of Parenting

Lessons From the Other Side of Parenting:  What I Wish I Knew From the Start 🧠 Realizing I’ve Become the “Older Dad” This week, I was scrolling through Facebook when I came across a friend’s post—he was clearly frustrated with his 12-year-old son’s lack of responsibility. I started typing out a reply, and somewhere between the lines, I realized something surprising: I’m now the “older dad.” The one with grown kids. The one who’s already walked the road from diapers to high school graduation. And while I didn’t always get it right (far from it), I’ve learned a few things along the way—lessons I’d love to share with any parent who’s in the middle of the mess, wondering if they’re doing any of it right. You only get to do this parenting thing once. Sometimes it feels endless, even overwhelming. But it’s a season that—when it’s gone—you’ll miss deeply. So here it is: the parenting wisdom I wish I had taken to heart from the beginning. 👶 Infant Stage: You Can’t Always Fix It ...

The Formation of Broken Multilingual Learners Stem Identities

Image
  The Data: According to research and data from the U.S. Census Bureau and educational studies, approximately 13.6 million students in the United States speak a language other than English at home , with Spanish being the most common heritage language. Among these, about 4.5 million students (as of 2023) are classified as English Learners (ELs), and the majority of these are heritage Spanish speakers. This means millions of students enter the school system as heritage Spanish speakers each year. These students often come from homes where Spanish is spoken, but their proficiency in Spanish varies, particularly in academic vocabulary. Their ability to succeed in both English and Spanish depends heavily on the educational supports they receive, as well as the type of program—such as dual-language, English-only immersion, or transitional bilingual education—they are enrolled in. The research of Thomas and Collier indicates that dual-language programs are most effective for these stu...
