[University Website Speed: Fewer Than Half of .edu Sites Pass Core Web Vitals](https://www.pagespeedmatters.com/resources/data-studies/university-website-speed)

We measured every .edu site Google has field data for. Only 48.3% pass Core Web Vitals on mobile. Higher education builds stable, responsive pages that are slow to load, and the enormous long tail of department and course sites is why.

Good Core Web Vitals by metric, university sites (mobile)

Good CLS (stability)

93.2% 

Good INP (responsiveness)

89.3% 

Good LCP (loading)

74.7% 

Source: Source: PageSpeed Matters analysis of 34,321 .edu origins with CrUX field data, May 2026.

Stability is the highest of any sector because academic pages are text-heavy and stable. Loading is the lone weak metric, and it caps the sector under 50%.

Homepage load time, fast vs slow .edu sites (mobile LCP)

Large online university (pass)

1.4s 

Private research university (fail)

2.6s 

Academic social network (fail)

2.8s 

University physics tool (fail)

8.1s 

Source: Source: PageSpeed Matters, mobile 75th-percentile field readings, May 2026.

A heavy interactive physics tool loaded on the homepage is the slowest recognizable .edu site at 8.1 seconds, roughly six times the fast leaders.
