Special programs of instruction are available for students who have been identified as English Language Learners (ELL). ELL classes are offered in all high schools except where a school has too few students. In schools with very small enrollments,students may be transported to nearby schools with larger student enrollments so that students can participate in the ELL program. 

When students enroll in Loudoun County, they are asked several home language questions on the student registration form. If a language other than English is indicated in any of these responses, an English language proficiency test is administered by a trained instructor.The test helps determine the student’s proficiency level, one factor that will help to determine what classes are most appropriate for the student.

Each student’s placement is determined on an individualized basis. Factors that should be considered before determining course placement include but are not limited to:

• Proficiency level

• Prior educational experience

• Student transcripts

ELL students must meet all graduation requirements in order to earn a diploma. In some cases, high school age students who possess little or no English skills or who have limited or no prior education may need more than four years to complete the credits and testing needed for graduation from high school. In these instances, age waivers for students 19 years or older may be submitted by the high school principal to the Assistant Superintendent of Student Services in order to grant the student an additional year in the LCPS school system.
