UC Davis Pass No Pass Deadline 2026: Complete Guide And Academic Deadlines

Navigating the Pass/No Pass (P/NP) grading option at the University of California, Davis (UC Davis) requires absolute precision, adherence to strict academic senate regulations, and strategic planning. Whether you are aiming to protect your grade point average (GPA), balance a heavy STEM or humanities course load, or fulfill specific major requirements, missing the Pass No Pass deadline at UC Davis can result in irreversible transcript marks. For the 2026 academic year, understanding the exact registration windows, unit caps, and college-specific policies is essential for maintaining academic good standing.

Critical 2026 UC Davis Pass/No Pass Academic Calendar and Deadlines

The Office of the University Registrar at UC Davis enforces strict registration timelines for changing grading options. Waiting until the final hours introduces technical risks, such as SISWEB latency or registration holds, which can prevent successful submission. The academic lifecycle for 2026 features distinct phases for undergraduate and graduate students adjusting their grade modes.

2026 Quarter-by-Quarter Deadlines

Note: The standard deadline occurs at the end of the 25th day of instruction at 11:59 PM via Schedule Builder. Submitting a petition between the 26th and 35th day requires college dean approval, a compelling justification, and a late processing fee.

Understanding UC Davis P/NP Grading Mechanics and Standards

Before altering a grading basis, students must understand how the university defines a passing grade under the P/NP framework. At UC Davis, a grade of Pass (P) is officially equivalent to a letter grade of C minus (C-) or better. Any performance falling below a C- is assigned a No Pass (NP) grade.

• Impact on GPA: Neither Pass (P) nor No Pass (NP) grades factor into your cumulative or quarter UC GPA.
• Unit Credit: Units earned with a grade of Pass count toward graduation requirements and total earned units. Units with a grade of No Pass earn zero credit and do not count toward graduation.
• Transcript Notation: A grade of NP remains on your academic record as a non-passing mark, though it does not pull down your numeric GPA. However, excessive NP grades can trigger academic probation or progress deficits.

College-Specific Rules and Unit Caps for 2026

Policies regarding the maximum number of P/NP units a student can take vary significantly depending on your specific undergraduate college at UC Davis. Graduate students face even tighter restrictions, often requiring graduate advisor and dean sign-offs for any non-letter grading options.

College of Letters and Science

Students in the largest college at UC Davis may take up to one-fourth (25%) of their total UC Davis units on a P/NP basis. However, courses required for a major or minor generally must be taken for a letter grade unless explicitly designated otherwise by the department.

College of Agricultural and Environmental Sciences (CA&ES)

CA&ES allows students to elect P/NP grading for elective courses, but mandates that all core, preparatory, and depth subject matter requirements for the major be completed for a standard letter grade. Transfer students must carefully evaluate their completed community college coursework to ensure they do not exceed allowable P/NP thresholds.

College of Engineering

Engineering majors face the most stringent limitations. Due to ABET accreditation standards and rigorous technical progression requirements, College of Engineering students are generally prohibited from taking required core engineering, mathematics, physics, and chemistry courses on a P/NP basis. P/NP is strictly restricted to general education and free electives.

College of Biological Sciences

Similar to Engineering, Biological Sciences prioritizes letter grades for all foundational lower-division science sequences (e.g., BIS 2 series, CHE 2 series, MAT 17/21 series). Electing P/NP for preparatory science courses can jeopardize medical school, dental school, or graduate program admissions prerequisites.

Strategic Pros and Cons of Using the Pass/No Pass Option

Choosing whether to switch to P/NP is a strategic decision that balances mental health, GPA preservation, and long-term professional aspirations.

Strategic Evaluation Framework

GPA Protection: Utilizing P/NP on a non-major elective allows you to insulate your GPA from a difficult grading curve or an unexpected heavy workload in upper-division coursework.

Graduate School Risks: Professional programs (medical, law, graduate, and pharmacy schools) often view large numbers of P/NP grades unfavorably, particularly in core science or analytical prerequisites. A Pass does not help your GPA, but a string of Passes in foundational courses can signal hesitation to admissions committees.

Step-by-Step Guide to Changing Your Grading Basis in 2026

Executing a grading option change requires navigating UC Davis's official digital portals. Follow this technical workflow to ensure your request processes correctly before the deadline.

1. Log into Schedule Builder: Access your Myucdavis portal using your Kerberos credentials and navigate directly to Schedule Builder.
2. Select the Target Course: Locate the specific course you wish to modify in your active schedule for the 2026 term.
3. Modify the Grading Option: Click on the course options menu and toggle the grading basis from "Letter Grade" to "Pass/No Pass".
4. Verify Major and College Constraints: Double-check that the course is not a mandatory requirement for your major, minor, or college core curriculum. Consult your major advisor if uncertainty exists.
5. Submit and Save Confirmation: Complete the submission. Crucial Step: Always save or screenshot the official confirmation receipt generated by the system. This serves as immutable proof in the rare event of a registration glitch.
6. Monitor Oasis: Check your Online Advising Student Information System (OASIS) portal 24 to 48 hours later to confirm that the grading basis adjustment is accurately reflected.

Frequently Asked Questions About UC Davis P/NP Deadlines

What is the absolute final deadline to change my grading option for Spring Quarter 2026?

The standard deadline is the 25th day of instruction, which falls on Friday, May 8, 2026, at 11:59 PM. Submissions between May 9 and May 22, 2026, require a late petition and dean approval.

Can I change my grade back to a letter grade after the P/NP deadline?

No. Once the 25th-day standard deadline passes, or the 35th-day late petition window closes, UC Davis policy prohibits changing a grading option from P/NP back to a letter grade, or vice versa.

Does a grade of Pass satisfy prerequisite requirements for subsequent courses?

Generally, a grade of Pass (equivalent to C- or higher) satisfies prerequisites that require a C- or better. However, many impacted departments and STEM sequences mandate a strict letter grade of C or better to advance to the next course in a series. Always verify department prerequisites.

How many P/NP units can I take per quarter?

While there is no strict cap on the number of P/NP units in a single quarter for most colleges, your cumulative total cannot exceed your college's maximum percentage (typically 25% of total units completed at UC Davis).

What happens if I miss the 35th-day late deadline?

After the 35th day of instruction, the Office of the University Registrar and college executive committees will not approve grading basis changes unless you can document extreme, verifiable extenuating circumstances (such as severe medical emergencies) via a retroactive late petition through OASIS.

Securing Your Academic Success at UC Davis

Successfully managing your academic trajectory at UC Davis demands constant awareness of institutional deadlines. Do not wait until the final hours of the 25th day of instruction to evaluate your performance. Consult with your College Advising Office and peer advisors early in the quarter, review your major roadmap on OASIS, and lock in your grading choices well ahead of the official 2026 deadlines.
