English as an Additional Language Support. There are mainly two types of EAL support provided at HJIS: - Pull-out support is for students who feel more comfortable receiving instruction at their level of proficiency. They are withdrawn from their English Language Arts classes all or part of the week by an EAL teacher and English is taught at a lower level until they gain confidence in entering the regular classes. - In class support is provided to students who feel comfortable being instructed at the school level, but need assistance in accomplishing tasks assigned during English Language Arts classes. The EAL teacher spends time inside the classroom with those students and they work together on the language activities so that the student is supported to become an independent learner.
