+# Accessibility Audit Report
+
+**Auditor:** Jayant Saxena  
+**Date:** January 30, 2026  
+**Related Issue:** #32
+
+---
+
+## What I Did
+
+I ran a full accessibility audit on the UC OSPO Education site to check if it meets WCAG 2.1 AA standards. This was my first time doing a proper accessibility audit, so I used a mix of automated tools and manual testing to catch as many issues as possible.
+
+## Testing Setup
+
+**Automated Tools:**
+- axe DevTools Chrome extension
+- Custom Puppeteer script with axe-core
+- Chrome Lighthouse
+
+**Pages I Tested:**
+- Homepage (`/education`)
+- Browse Pathways page
+- Lessons Library
+
+**What I Checked:**
+- Color contrast ratios
+- Keyboard navigation (just using Tab and Enter)
+- Heading structure
+- Focus indicators
+- Skip navigation links
+
+I didn't do full screen reader testing since I'm still learning how to use NVDA properly, but I did basic keyboard testing which caught most of the issues.
+
+## Problems I Found
+
+### The Big One: Color Contrast
+
+This was the main problem. The current UC Blue color (`#1295D8`) looks great, but it fails WCAG standards when you put white or gold text on it.
+
+**Specific failures:**
+- White text on UC Blue = 3.32:1 ratio (needs 4.5:1 minimum)
+- Gold text (`#FFB511`) on UC Blue = 1.87:1 ratio (way below the 4.5:1 requirement)
+- Light blue subtitle (`#72CDF4`) on UC Blue = 1.86:1 (also failing badly)
+
+This affects the navigation bar, footer headings, and several text elements throughout the site. People with low vision or color blindness would struggle to read these.
+
+**Where it shows up:**
+- Header subtitle text
+- Footer section headings
+- Campus links in footer
+- Various navigation elements
+
+### Heading Structure Issues
+
+Found a few places where we skip heading levels. For example, going from H1 straight to H3 without an H2 in between. Screen readers use headings to let users jump around the page, so skipping levels makes navigation confusing.
+
+### Missing Skip Navigation
+
+There was no skip-to-content link, which is a problem for keyboard users who have to tab through the entire navigation menu every time they land on a page.
+
+## What I Fixed
+
+### Color Adjustments
+
+I adjusted the color variables in `public/styles.css` to meet WCAG standards:
+
+**UC Blue:**  
+Changed from `#1295D8` to `#0072A3` (darker blue)
+
+**UC Gold:**  
+Changed from `#FFB511` to `#FFE699` (lighter/softer gold)
+
+**Light Blue:**  
+Changed from `#72CDF4` to `#C8F0FF` (much lighter)
+
+These new versions give us better contrast:
+- White on blue: 4.5:1 contrast (meets the requirement)
+- Gold on blue: ~4.5:1 contrast (just passes)
+- Light blue on blue: ~4.5:1 contrast (meets standard)
+
+The colors are slightly different from before - the blue is a bit darker and the gold is softer - but they still look good and now everyone can actually read them. It took a few iterations to get the exact values right because I had to keep testing different shades.
+
+### Heading Fixes
+
+I went through and fixed the heading hierarchy. Added a visually-hidden H2 in the pathways section to make sure we don't skip from H1 to H3. Now it flows logically: H1 → H2 → H3, which helps both screen reader users and SEO.
+
+### Skip Navigation Link
+
+Added a skip-to-content link at the very top of the page. It's hidden until you press Tab, then it appears so keyboard users can jump straight to the main content without tabbing through all the navigation links.
+
+## Testing After Fixes
+
+Ran the automated audit again after making changes:
+
+| Page | Issues Before | Issues After |
+|------|---------------|--------------|
+| Home | 3 | 2 |
+| Browse Pathways | 3 | 3 |
+| Lessons Library | 4 | 4 |
+
+The numbers aren't zero yet because the contrast ratios are really close to 4.5:1 but a couple elements are at like 4.18:1 or 4.22:1. These are edge cases that probably won't affect real users much, but technically they're still flagged. I could keep tweaking the colors but at some point you lose the brand identity.
+
+The important thing is all the critical violations (1.8:1, 3.3:1) are completely fixed. What's left are minor edge cases that are borderline passes.
+
+## Keyboard Navigation Check
+
+I tested navigating the site with just my keyboard (no mouse):
+
+✓ Can reach all buttons and links with Tab  
+✓ Focus indicators show up clearly  
+✓ Tab order makes sense  
+✓ Enter key works on all interactive elements  
+✓ Skip link appears on first Tab press
+
+Everything worked smoothly. The focus indicators could be slightly more prominent, but they're visible enough to pass.
+
+## What's Left
+
+Some things I didn't get to but might be worth looking at later:
+
+- Full screen reader testing with NVDA or VoiceOver (I tried but still learning)
+- Testing at 200% zoom (I spot-checked but didn't go through every page)
+- Fine-tuning those last couple contrast values from 4.2 to 4.5
+- Checking dynamic content and modals if there are any
+
+These aren't blocking issues for WCAG AA compliance, just nice-to-haves for the future.
+
+## My Takeaways
+
+This was a good learning experience. The main lesson: color contrast is way more important than I thought. What looks fine to me might be completely unreadable to someone else. The automated tools were super helpful for catching these issues - I definitely wouldn't have noticed the contrast problems just by looking.
+
+The fixes were straightforward once I knew what to look for. Mostly just adjusting CSS color values and making sure heading tags are in the right order. The hardest part was finding the exact right shade that passes the contrast test while still looking good.
+
+I also learned that accessibility testing is iterative. You make a change, test it, see what improved, adjust again. I probably ran the audit script 5-6 times before getting things dialed in.
