that are best addapted to your business


Since 2014 when our cooperation with International Language Institute began, we have been effectively and efficiently improving the command of the English language of our employees, which translates directly into the quality of customer service we offer.


ECOLAB is the global leader in the area of professional solutions related to hospital hygiene, textiles, food production, water recycling, or the energy sector. The group employs about 50,000 people all over the world. Our international character requires of us that we freely communicate in different foreign languages, this is why continuous improvement of the linguistic competence of our employees is the priority. International Language Institute carries out individual audit of the command of languages for us and adapts the form of classes to the needs of the student. The school offers individual and group classes both at our premises and outside. The classes are held by experienced teachers, including native speakers, in locations all over Poland.


Stable position in 80 countries of the world and the focus on the cement, aggregates and concrete makes Lafarge Holcim the world leader in the construction materials industry. Due to the international character of the group and the cooperation with local and foreign clients, linguistic knowledge of our employees is of key importance for us. Our employees and managers speak English every day to communicate with suppliers and clients all over the world in an effective and efficient manner. Since 2015, our employees have had the opportunity to improve their linguistic competencies also with the help of courses organised by International Language Institute all over Poland: in Gdańsk, Kielce, Koszalin, Kraków, Małogoszcz, Kujawy, Poznań, Rudawa, Warsaw, and Wrocław.


Reesco success is based on the qualified and competent team, composed of practitioners with many years of experience in engineering, real estate appraisal, architecture and construction site management. Their knowledge and experience guarantee that the expectations of event most demanding clients are met. We offer our services to both Polish and foreign clients, which is why linguistic competence is a priority for us. We have been looking for a business partner who would support us in learning and in improving linguistic skills of our personnel. Our employees use their linguistic skills to attend meetings with our partners, to give reports and presentations. International Language Institute held a comprehensive audit of foreign language levels in our employees and adjusted the methodology to fit our needs. At the moment, our employees study the language in 6 groups, depending on their language level. We have noticed a marked improvement in the quality of work and the ease of using the language by our employees.


Attending English language courses is one of the development solutions we offer to our employees. Anyone who is interested in such a course, including top managerial personnel, may attend it. When we were looking for a partner in the area of language courses, we were looking for a company that can offer language learning to people that work in different locations in Poland. As it turned out, International Language Institute met that requirement. International Language Institute’s teachers are always well-prepared, punctual, committed, and the classes they teach are interesting for our employees. The courses are adapted to the current command of the language in the group and take our business needs into consideration.


Our mission is to create the best possible working environment for our employees, and the key to do that is for example offering a wide range of employment benefits, including foreign language learning. At GK Interia, we have a policy of open access to free language courses for our employees. Our employees have the opportunity to attend individual or group courses, at our premises and in the schools of International Language Institute all over Poland. Before each course, ILI carries out an audit of the current language level to better adapt the level and scope of the language course to the needs of our employees, ILI also offers us a possibility to analyse the attendance and the learning progress. Students of ILI’s language courses appreciate high level of commitment exhibited by the teachers, their competencies and the fact that they are well prepared for the classes.

Since March 2016, International Language Institute has been working with our employees to improve their command of English language. Knowing a language promotes more spontaneous communication and positively affects how the brand is recognized, and the employees are comfortable in their relations with clients, which in turn translates into better results of their work. Cooperation with International Language Institute is at a very high level. The Company took every effort to understand our needs.
