In 2022, four partner organisations were awarded a three-year Erasmus+ grant titled "Building Bilingual Programs in Elementary Schools". The grant has allowed us to create resources to support educators working in schools with bilingual programs, Numerous heads of schools, language specialists, and classroom teachers are independently striving to establish bilingual programs. Our objective is to facilitate communication and foster connections among these professionals from different backgrounds, with the overarching aim of creating an environment where we can collectively learn and grow. Where needed and possible we will translate the project outcomes into the languages of Czech, Spanish, French and Estonian. Furthermore, we saw the need to offer guidance by collecting expert knowledge and actual experience of effective administrative and classroom practices, which would help elementary schools across Europe achieve strong and developmental bilingual programs.
