Shawna Longo

Sussex County Teacher of the Year
(2021–2022)

Smile Zemi exceeded
my expectations!

What I really like about Smile Zemi is its ability to adapt to the students' individual needs and academic abilities. Twenty percent is an amazing increase in students' abilities in a short period of time.

Blian Byrne

Tulsa Trail School Principal

Smile Zemi is great for making up for learning loss.

What I’ve seen from Smile Zemi’s pilot program in the short time is that it's been very effective. 29 percentage point increase for the average of second-grade students — it wasn't just a bandage to the problem.

Monica Crudele

Borough School Principal

Children acquire fundamental skills in an enjoyable way.

Our students were able to see tremendous gains in the area of spelling and in grammar. Particularly, we went up fifteen percentage points in the area of spelling and thirty-five percentage points in the area of grammar.
