The most commonly used tools include:

1. Language tests (entry, progress, and final exams).

3. Attendance and participation reports.
4. Feedback from learners and their managers.
5. Data from e-learning platforms and language apps.

How Lang LTC measures language training effectiveness

At Lang LTC, we treat performance measurement as an integral part of the training process – not just at the end, but throughout the entire course. This approach provides our clients with complete insight into learning progress and the ability to optimize training in real time. Here’s how our system works:

1. Initial surveys

We identify participants’ needs and align the course content with the company’s business goals

2.  Placement and ongoing teacher communication

Each learner is placed in a group matching their level and needs. Throughout the course, we stay in regular contact with teachers to monitor progress and adjust as needed

3.  Monthly language goals

Each teacher sets monthly learning goals for their group and reports on the results. This allows real-time tracking of progress

4.  Progress, mid-term, and final tests

These help measure knowledge gains both individually and at the group level

5.  Mid-term satisfaction surveys

We collect structured feedback on lesson quality, materials, and teacher performance

6.  Regular HR reporting

We provide clear and comprehensive reports including:

• Attendance,
• Test results,
• Goal achievement tracking,
• Identified challenges  and recommended improvements.

7.  Methodological class observations

We regularly observe classes to assess teaching quality, methods used, and participant engagement

8. Monitoring attendance and cancellations

Each month, we analyze the number of canceled classes and participant absences. This helps us detect and address obstacles to learning early on

Why measure language training effectiveness?

1.  Because only what’s measurable can be improved or optimized
2.  Because data gives you solid ground for reporting and decision-making
3.  Because visible progress motivates both learners and their managers
