The article presents the key activities of a recent educational project (Lifelong learning of teachers of Romanian, English and French, in the knowledge society, POSDRU ID 87/1.3/S 62536), based on a teacher training program with ICT support. This project is implemented by Braila County School in partnership with the University of Bucharest, SIVECO Romania and TEHNE - The Center for Development and Innovation in Education, sustained in January 2011 - December 2013. Out of the 5000 teachers included in the target group were trained, using a form of applied curriculum, exchange experience and on-line collaboration. The aim of this paper is to describe an interesting link between the training curriculum and e-learning platform. We illustrate the results of the two training modules available on the project platform (Curriculum design and Differential education), both in interactive and text forms. The courses offered new curriculum design, implementation and assessment competences, adapting to pupils' features and current trends in (native and foreign) language teaching; new competences to develop learning experienced based on differentiated teaching, using interactive teaching-learning methods; develop capacities to interrelate within the professional community. We will present some evaluation results of the final report, including the impact of technology in teacher training. In this sense, the portal dedicated to teachers of Romanian, English, and French was appreciated as an efficient tool for professional communication. In synthesis, the project offered teachers new opportunities to develop a teaching career, through the certified training program and modern digital resources. In order to understand Mastery learning teaching models, this paper include a number of concrete examples of the lesson plans launched trough the national competitions, and presented during the two National Conferences.
