Students enrolling in the district are assessed with the WIDA Screener to help identify whether a student is a candidate for EL services. A student who achieves a 5.0 or above in the oral language composite (speaking and listening) AND a 4.2 literacy composite (reading and writing) is considered English proficient.

EL students are assessed each year to determine their progress toward English language proficiency with the ACCESS Assessment. This computer-based, adaptive test measures a student's proficiency in reading, writing, listening, and speaking. ACCESS is a required assessment in the state of Illinois for all students eligible for EL services and is administered in January and February.

Parents will receive the results of the assessment along with information stating whether the student continues to be eligible for English language services. Students who achieve an overall composite score of at least 4.8 will exit the EL program. After exiting, the Director of Multilingual Services will continue to consult with classroom teachers and monitor the student's progress for a period of two years.

At any time, a parent may decline EL services. Parents must submit this request in writing to the Director of Multilingual Services & Family Engagement. Per the Illinois State Board of Education, students who are eligible for service, but whose parents refuse, must continue to take ACCESS annually until they earn a 4.8 overall composite score.

We take a holistic view and look at what grade a student has completed in their home country, as well as credits earned, and the student’s age.

A credit is how we measure completed courses for students. Every class a student takes each semester counts for 0.5 credits, except for Physical Education and Consumer Education, which count for 0.25 credits. Students earn credits for grades A, B, C, and D, and no credit for grades of F.

In order to graduate, D155 students must obtain 20.25 credit units. 

(1) At least one year of Social Science must be United States History. Students are also required to fulfill the global education requirement during their freshman or sophomore year and one semester of Civics. Courses that meet the Civics requirement will be noted in the Social Science section of the course catalog.

(2) One credit of Mathematics must be in Algebra I, and one credit must be a course that includes Geometry content.

(3) One credit of electives must be in art, foreign language, music, or vocational education.

(4) Courses that fulfill the consumer education credit will be noted in the course catalog. 

(5) The Career Experiences Program (CEP) requirement will be met by successful completion of all tasks assigned in the required seminar/advisory class each year.  This graduation requirement begins with the class of 2025.

GPA stands for grade point average, which is an average of your student’s final semester grades each semester. The GPA is calculated each semester and is an average of your student’s coursework over four years. The GPA is one of the things that colleges will look at for admission into their school.

A counselor will be assigned upon registration. Students are supported by their counselor, social worker, psychologist, dean, and nurse.
