What Is a Passing Grade? High School, College & Pass/Fail

High school: 60% is usually the line

In most US high schools, the lowest passing grade is a D−, and it starts at 60%. Anything below that is an F, which earns no credit for the course. On the familiar letter scale that most districts use, the passing zone looks like this:

That said, 60% is a convention, not a law. Plenty of schools and individual teachers set a higher bar — some use 65% as the passing floor, and some courses require a C to move on. If you're staring at a raw percentage and want to know which letter (and whether it clears the line), the Percent to Letter Grade converter maps any score onto the standard scale in a second. And here's the part students miss most: passing a class is not the same as satisfying a requirement. A D in Algebra I might earn the credit but still fail to meet a "C or better in math" rule for graduation or for the next course in the sequence. Passing keeps the credit; it doesn't guarantee the door opens.

College: passing the class vs. passing for your degree

College is where the single-number idea of "passing" really falls apart, because there are two different thresholds running at once.

The first is institutional: to earn credit and stay in good standing, most colleges treat a D (1.0) as the lowest passing grade for a course overall. Below that is an F, worth zero grade points, which drags your GPA down and earns nothing.

The second threshold is programmatic, and it's usually stricter. A grade that passes for your transcript may not pass for your degree plan:

• Major and prerequisite courses commonly require a C (2.0), and sometimes a C−, to count. A D in a course your major depends on often has to be retaken.
• Prerequisite chains gate the next course: many science and math sequences won't let you register for the next class without a C or better in the one before it.
• Transfer credit frequently won't move a D between institutions — receiving schools often accept only C-and-above work.
• Graduate and professional programs may set the bar even higher, sometimes requiring a B− in core coursework.

So a 68% — a D+ — might be "passing" in the sense that it appears as credit on your record, while simultaneously failing to satisfy the requirement you took the class for. When you're checking whether a percentage clears a specific "C or better" rule, the Percent to Letter Grade converter tells you exactly which letter your score lands on. The rule of thumb: for anything load-bearing — your major, a prerequisite, credit you plan to transfer — aim for a C at minimum, and read the catalog for the exact requirement, because policies vary by school and by program.

How Pass/Fail (P/NP) works

Pass/Fail — sometimes labeled Pass/No Pass (P/NP) or Credit/No Credit (CR/NC) — swaps a letter grade for a simple binary. You either clear the passing threshold and get a P, or you don't and get an NP. It's popular for electives outside your major, where students want to explore a subject without risking their GPA on a harder-graded class.

The key mechanic is the GPA impact, and in the usual case there isn't one. A P normally earns the credit hours but contributes no grade points, so it neither lifts nor lowers your GPA — the course is invisible to the average. An NP typically earns no credit and, at many schools, also stays out of the GPA calculation.

But "usually" is doing real work in that sentence, and this is where you have to read the fine print:

• What counts as a "Pass" varies. Some schools set the P threshold at a D (any passing letter converts to P); others require a C− or C. A C− that would have been fine as a letter grade can become an NP under a stricter Pass/Fail policy.
• A failure may still bite. At some institutions a non-passing Pass/Fail grade is recorded as an F that does count in your GPA — the opposite of the "no penalty" assumption.
• There are usually limits. Colleges often cap how many Pass/Fail credits count toward a degree, and bar Pass/Fail for major, minor, or general-education requirements.
• Deadlines and reversibility differ. Some schools let you switch a course to or from Pass/Fail only within a set window, and some won't let you convert a P back to a letter grade later.

If you're weighing whether to take a class Pass/Fail and want to see how including or excluding it changes your average, the Pass/Fail Calculator lets you model it before you commit — useful precisely because the "no GPA effect" rule has so many local exceptions.

The financial-aid angle: SAP

One reason passing matters beyond the transcript is Satisfactory Academic Progress (SAP), the standard you have to keep to stay eligible for federal financial aid. SAP generally has three parts: a minimum cumulative GPA (commonly 2.0), a completion rate — you must complete a set share of the credits you attempt, often around 67% — and a maximum timeframe to finish your program.

Failed courses and withdrawals hurt the completion-rate piece, because they count as credits attempted but not earned. And note that a Pass/Fail course still counts as attempted credit, so leaning heavily on it doesn't exempt you from the pace requirement. None of this is cause for alarm if you're passing your courses — but a run of Fs, NPs, or drops can put aid at risk, and the exact numbers differ by institution. As with everything here, the reliable move is to confirm the specific SAP standard with your financial-aid office rather than assume the typical figures apply to you.

The bottom line

There is no universal passing grade, only passing grades relative to a purpose. A D at 60% passes a typical high-school class. A C at 70% is what a college major or prerequisite usually demands. A P keeps a class off your GPA — unless your school's policy says otherwise. The single habit that protects you across all of it: before you rely on a grade, find the actual requirement in your school's catalog or registrar policy, because the thresholds genuinely vary from one institution to the next.
