Mariana Cardona - Country Day School

English Language Development Teacher

I started my teaching career at Country Day School in the year 2000 as a Prep teacher assistant in the Early Childhood house, while pursuing my English Teaching Bachelor Degree from Universidad Latina de Costa Rica. 

In 2003 I was invited to the Elementary school to become part of the English Language Development team. 


Up to this date, I have been welcoming, teaching, and helping English Language Learners, 1st to 5th grade, from beginner to advanced levels. I strive to make all students feel confident in the environment as they learn the language, and as I learn from them.

I continuously participate in Professional Learning Communities creating and revising ELD curriculum for beginner primary students. I proctor DRA, WIDA, and MAP assessments throughout the year. I have attended various educational training such as the TESOL convention and other literacy and English workshops and seminars.

Throughout my years at CDS I have formed part of Sunshine Committee, Health Fair Committee, and Book Month. This year, during virtual teaching, I am a co-teacher in a 4th-grade classroom.
