ELL students will likely to need more time to process the information on lessons, quizzes, test, and often will have difficulty comprehending the content of test items. Especially due to unfamiliar language or cultural references.

Six to ten years to reach grade-appropriate reading and writing proficiency in English, could only truly accomplished by supporting ELL students in all aspects. Their worries and anxiety to learn in class can be improved with support and ecouragement from their teachers and staff. I find that being humorous and striving to make the lesson at hand relateable to them helps significantly.

I had to remember his pace of remembering our subject was slower and difficult due to reading and writing in the English language in itself.
