I want to be straightforward with you: **my knowledge cutoff is early 2025**, so I can't reliably tell you what's most popular specifically in 2026.
## What I Can Share (as of my knowledge)
Leading K-12 Student Information Systems (SIS) that were prominent included:
- **PowerSchool** - widely used, large market share
- **Infinite Campus** - strong in many US districts
- **Skyward** - popular in certain regions
- **Frontline Student Information System**
- **Alma** - growing cloud-based option
- **Aeries** - common in California
- **Synergy (Edupoint)**
- **Illuminate Education**
## For Current 2026 Information, I'd Suggest:
- **EdWeek Market Brief** for market research
- **Software reviews on G2 or Capterra**
- **CoSN (Consortium for School Networking)** reports
- **State education agency procurement lists**
- Asking peers in **district administrator networks**
The SIS market was experiencing consolidation and cloud migration trends, but specific 2026 rankings could reflect changes I'm unaware of.
Would you like more detail about any of the systems I mentioned based on what I do know?
