Introduction

As generative AI becomes more prevalent in academic settings, universities face new challenges in maintaining academic integrity. When students wonder "do UCs check for AI" in their work, the answer is nuanced. The University of California (UC) system has made the decision not to require AI writing detectors on its campuses, instead focusing more on educational approaches to use AI. This decision raises interesting questions about how AI should be used in academic processes and the role, if any, detection tools should have. This article provides an overview of the official policies at each UC campus, as well together as the UC system's overall policy and philosophy regarding AI detectors and AI in general in education.

Why UC Campuses Are Cautious About AI Detection Tools

The UC system's reluctance to adopt AI detection tools stems from several core concerns:

1. Accuracy Concerns: AI detectors often generate inaccurate or unreliable results. This can lead to false positives, incorrectly flagging student work as AI-generated.

2. Equity Concerns: Multilingual students or students with unique writing styles may be more likely to be flagged by AI detectors, resulting in unfair treatment.

3. Privacy and Data Protection Concerns: Uploading student work to third-party AI systems can raise privacy, FERPA compliance, and intellectual property concerns.

4. Due Process Concerns: UC policies emphasize evidence-based academic integrity approaches, which require objective and reliable evidence. Probabilistic AI scores may not meet these due process standards.

The Current State of AI Detection in UC Universities

What UC Campuses Are Doing Instead

While many UC campuses have declined to use AI writing detectors, they are not rejecting AI technology altogether. Instead, the UC system is actively developing a forward-thinking approach to AI integration, grounded in AI literacy, pedagogical innovation, and privacy-conscious technology adoption.

● AI Literacy: UC campuses are providing instruction on how the various AI tools function, their limits, and when it is appropriate for students and faculty use them. For example, UCLA, which also has no AI detectors, describes AI as "an instrument that we all engage with" and provides teachers resources on how to create clear AI policies in their courses.

● Pedagogical Innovation: UC campuses are redesigning tests to assess process rather than a final product that could be produced through AI. For example, UC San Diego promotes assignments that prioritize iterative drafting, reflective writing, and oral articulation (of work that only a student can do): AI can’t easily mimic these skills. Artificial Intelligence in Education.

● Supported AI Tools: UC Merced, as well as other UC campuses, has a list of AI tools that have been approved (including Microsoft Copilot and Zoom AI) and are therefore compliant with privacy and data protection standards. Find UC Merced's AI tool guidelines here.

Taken together, the UC response to AI is neither defensive nor punitive. The lack of AI detectors is simply not an oversight but a conscious decision that reflects values shared across all UC campuses: How students learn to use AI responsibly is more important than trying to catch them with unreliable detection technology.

Conclusion: Do UCs Use AI Detectors?

So, do UCs use AI detectors? Ultimately, no. The stance of the University of California on the use of AI writing detectors is more than just a stance on the use of a particular technology. When students ask "do UCs check for AI?" they should be told that the majority of UCs have decided against them. But UCs have opted for a more holistic approach to AI technology integration that is based on AI literacy, pedagogy, and privacy. In other words, UCs are setting an example in higher education for how AI should be used responsibly.
