12 English levels, plus TOEFL Preparation Course

Monday-Friday, 25 hours per week

ILI offers an intensive English ESL day program with classes in two locations: Dupont Circle in Washington, D.C., and Gaithersburg in Maryland. In Washington, D.C. we offer 12 different 4-week levels, ranging from beginner to university level, plus an 8-week TOEFL Preparation course.  Each class includes instruction in the following areas: Listening, speaking, grammar, reading, and writing.

Level Description:

These are the beginning levels for students who have not studied English before or who have studied only a small amount of English for a short time. The classes include these things.
  • Basic vocabulary, grammar, and conversation
  • Simple reading and writing (including the alphabet, if needed)
  • Listening practice
  • CD/DVD program
  • Pronunciation
  • Yes/no and information questions
  • Spelling, dictation
These are low-intermediate levels. The students begin working through a grammar book that explains basic English structures. In addition, a reading/writing book builds students’ reading skills through vocabulary and comprehension questions and helps the students learn about simple mechanics and organization for writing sentences and single paragraphs.
These are intermediate levels. The activities in these levels become more advanced. The textbooks have a wider vocabulary and include more complicated structures. Students continue to work on single-paragraph essays and on more complicated listening, speaking, and reading activities.
These are high-intermediate levels. The lessons and skills taught are more academic. Students write three multi-paragraph essays, paying attention to correct paragraph structure, organization, and detail. Students listen to reports about a variety of topics and work on exercises that include listening for details, synthesizing information from listenings and making inferences. In addition, these levels may include debates, role-play, class discussions, student presentations, and other speaking activities.
These are advanced levels. The students work on complex structures in the grammar textbook. The writing assignments include multi-paragraph essays. Students work with more complex topics in listening, speaking, reading, and writing. Students might be asked to prepare an oral presentation or lead a class discussion.
This is the university and professional level. The class prepares students for an American college or university, a U.S. corporation, or an international organization. As much as possible, the students use authentic English texts: American newspapers, magazines, novels, short stories, poems, essays, radio programs, TV programs, and video presentations. Students do a variety of writing activities. These writing assignments might include a biography, an analysis of something read in class, a resume, a business letter, a practice TOEFL essay, or a response to a student presentation. Students give oral presentations or lead discussion groups. There is extensive vocabulary work. Instructors review points of grammar based on student errors in speaking and writing.

Students must be at the F level and must receive either a score of 70 on the placement test or the Program Coordinator’s approval to take this course.

Payment Policy:

New students:  Tuition for the first cycle (4 weeks) in the amount of $780 has to be paid entirely before the student is allowed in class. If the student is enrolling for less than 4 weeks, all tuition has to be paid before a student is allowed in class.

Continuing students:  Tuition is due the Monday after the last payment is up. A late fee of $15.00 is automatically added to any payment not received by Wednesday and increases by $15 for each week late. ILI reserves the right to disallow students in class who have not paid their tuition. Continuing students with unpaid tuition, books, or fees from a previous cycle will not be allowed to re-enroll for a new cycle until such balance is paid in full. Continuing students wishing to pay for less than 1 cycle at a time can choose one of the following payment schedules:

English or TOEFL
Every 2 Weeks$400
Every 3 Weeks$595


At the end of each four-week cycle, a student may pass to the next level if he/she has a grade average of 70% and an attendance average of 80%. If the student’s grade average is below 70%, he/she will need to repeat the level. If the student’s attendance is below 80%, he/she will need to repeat the level. The student’s grade is determined by averaging five skill areas: an average of the grammar chapter test grades, the final listening assessment, the final speaking assessment, the final reading assessment, and the final writing assessment.

Certificates & Evaluations:

All students who complete their program are awarded a certificate of attendance at the end of their studies upon request. All students are continuously evaluated and an evaluation report is available at the end of their studies. In order to qualify to receive a certificate of attendance or an evaluation from ILI, a student must maintain attendance of at least 80%.
