Rediker Software review

A reliable, veteran SIS covering the full student lifecycle.

Verdict

Rediker's AdminPlus SIS is a veteran in the space, offering a reliable, feature-rich platform that covers the full student lifecycle from admissions to graduation.

What customers praise

The modular approach allows schools to purchase only the components they need, such as the admissions portal (Admissions Plus Pro) or parent communication app (ParentPlus).

What customers criticise

The software is a desktop-based application with web portals, which feels less modern and flexible than the fully cloud-native platforms of competitors like Alma.

Best for

K-12 schools of all types looking for a long-standing, stable provider with a comprehensive suite of modular software, including admissions and mobile apps.
