How to Choose the Best English Course: A Usable Evaluation Framework
"The best English course" is not an absolute category. The programme that is best for an adult starting from zero may not be best for a student who needs a specific exam score within two months. For this reason, the right question is not "which course is best" but "which course is best suited to my goal, level and timetable". Rather than recommending an institution, this guide gives you a 100-point framework, a trial-lesson checklist and questions that expose weak programmes, so you can evaluate any institution yourself.
The 100-point evaluation framework
The weighting below is arranged according to the relative importance of the factors that determine outcome in language learning. Score each institution you evaluate against these headings and compare the totals.
| Criterion | Weight | Full-score condition |
|---|---|---|
| Class size and speaking time | 25 | Written upper limit of 8 or fewer |
| Instructor quality and continuity | 20 | Has a teaching qualification and the same instructor is guaranteed throughout the term |
| Placement assessment and progression criteria | 15 | Free placement including a speaking component; written and oral end-of-level assessment |
| Feedback quality | 15 | Written assignments are corrected individually, not just graded |
| Programme-goal fit | 10 | You are directed to the right programme if your level is not suitable |
| Travel and continuity | 10 | One-way travel under 45 minutes |
| Institutional assurance and contract | 5 | Ministry institution code and written refund, freeze and absence clauses |
1. Class size and speaking time — 25 points
Speaking ability is directly proportional to the time a student actually gets to speak in class. In a class of 20, the share of active speaking time per student in a 90-minute lesson is limited to a few minutes. Ask the institution for the written upper limit on class size; the phrase "an average of 8 students" does not rule out classes of 16. For full marks, the upper limit must be 8 or fewer in writing.
2. Instructor quality and continuity — 20 points
Two things need to be assessed together: the instructor's language teaching qualification (CELTA, DELTA or a degree in English language teaching) and whether the same person will continue throughout the term. A change of instructor mid-term visibly disrupts the learning curve. "Native English-speaking instructor" is not on its own an indicator of quality; a native speaker without teaching qualifications may struggle to explain why your mistake is a mistake.
3. Placement assessment and progression criteria — 15 points
Does the institution carry out a free placement assessment before enrolment that includes a speaking component? A multiple-choice grammar test alone is not enough; learners in Turkey frequently show a one-step gap between reading level and speaking level. Also ask on what criterion progression from one level to another is made. In programmes that advance students purely on attendance, learners progress with an incomplete foundation and typically stall around B1.
4. Feedback quality — 15 points
Are your written assignments corrected individually, or only graded? An assessment that includes no correction is not feedback. Is regular, concrete guidance given on your speaking performance?
5. Programme-goal fit — 10 points
Does the institution direct you to the programme suited to your goal, or does it sell everyone the same package? A good sign: if your level is not suitable, the institution recommends general English first rather than exam preparation. This is not a lost sale but correct guidance.
6. Travel and continuity — 10 points
The most common cause of failure in a language course is not a lack of ability but dropping out. A programme that takes more than 45 minutes one way adds roughly 9 hours of travel to 6 hours of weekly lessons. Assess the building's location together with your own route.
7. Institutional assurance and contract — 5 points
Does the institution have a Ministry institution code? Language courses in Turkey operate under Private Education Institutions Law no. 5580, and licensed institutions are required to issue a Ministry-approved learner contract. Refund, enrolment-freeze and absence clauses should be in writing.
Bring price into play only after calculating the total score. Deliberately keeping price out of this framework is intentional: first determine which programme will actually work, then choose the one that fits your budget. For a unit-cost calculation, see our English course prices guide.
What should you look at in a trial lesson?
A single trial lesson tells you far more than a brochure or website. When you attend, measure the following:
- Distribution of speaking time: How much of the lesson does the instructor speak, and how much do the students? In a good lesson, students collectively speak more than the instructor.
- Your own speaking time: How many minutes did you speak during the lesson? If it is below 8–10 minutes in a 90-minute lesson, the class size is too large.
- The way errors are corrected: Does the instructor correct mistakes immediately, or note them without disrupting the flow and address them together at the end? The latter preserves speaking fluency and is a more advanced technique.
- Use of Turkish: What proportion of the lesson is conducted in Turkish? Some Turkish is necessary at beginner levels, but from B1 upwards the lesson is expected to be conducted predominantly in English.
- The class's actual size: Does the advertised number match the number of people in the room?
- Level fit: Can you understand roughly three quarters of the lesson? If you understand nothing, the level is too high; if you are not challenged at all, it is too low.
Questions to ask the institution and warning-sign answers
| Question | Weak answer | Why it matters |
|---|---|---|
| "What is the upper limit on class size, can you give it in writing?" | "It's usually not crowded." | Speaking time is directly tied to class size |
| "How many minutes is one lesson hour?" | Turning the topic into a package price | A 40, 45 or 60 minute difference creates a hidden gap of up to 30% between offers |
| "Will this group's instructor be the same person throughout the term?" | "Our staff pool is very large." | A mid-term instructor change disrupts the learning curve |
| "What determines level progression?" | "You pass if your attendance is sufficient." | Attendance-based progression leads to a stall around B1 |
| "Are my writing assignments corrected individually?" | "Of course, they're followed up." | An assessment with no correction is not feedback |
| "How many total lesson hours do I need to reach my goal?" | Giving a duration without a placement assessment | Only this number determines the total cost |
| "Can I see the refund clause in the contract?" | "We'll sort it out at enrolment." | Verbal commitments cannot be proven in a dispute |
| "What happens if the group doesn't open?" | "It will definitely open." | A critical risk for learners with an exam date |
An institution's quality is measured by its willingness to give these answers in writing. Verbal commitments cannot be proven in a dispute.
How should you read reviews?
Student reviews are valuable, but should be read with a filter:
- Vague praise is weak evidence. "Great course, I recommend it to everyone" carries no information. A valuable review is concrete: what level did they start at, how far did they get and in how long, which instructor did they work with.
- Look at the clustering of dates. A large number of five-star reviews gathered in a short time window may not be organic.
- Responses to negative reviews are the most informative. How the institution responds to a complaint shows what to expect if you have a problem.
- Look at the type of complaint. "There was no parking" and "I was moved up a level but learned nothing" do not carry the same weight. The latter points to a structural problem.
Unrealistic promises
- "Fluent English from zero in 3 months." According to the guided learning hours published by Cambridge English, reaching B2 level from zero requires approximately 500–600 lesson hours. At 6 hours a week, that is over 18 months.
- "Guaranteed exam score." No institution can guarantee an exam score; the candidate's own performance determines the result.
- "All native English-speaking instructors." Not on its own an indicator of quality; what matters is teaching qualification.
- "Unlimited speaking club." Separately confirm whether the club is included in the lesson hours and how often it runs.
"Best" depends on your profile
- An adult starting from zero: Priority is a face-to-face format, small class size and a location that supports continuity. See English course in Istanbul.
- Those needing an exam score by a specific date: Priority is the number of mock exams and writing feedback. See IELTS, TOEFL and iTEP course.
- A student wanting to skip the preparatory class: Priority is alignment with the target university's exam format. See preparatory exemption course.
- A working professional: Priority is flexible hours, a hybrid format and a function-based curriculum. See Business English course.
- Parents: Priority is the instructor's experience with children's groups and age-group homogeneity. See English course for children.
