Riga Secondary School 34 is a school with a profound teaching of English. The interest in CLIL teaching appeared after the good results in the immersion programme in Primary School, where Science, Maths and Arts were taught in English by the English language teachers. The teachers of maths, science and economics participated in CLIL theoretical courses in the autumn of 2014. In 2014 the voluntary English teaching/learning was organized for subject teachers. In 2014/2015 the integrated programme for teaching science and English for Form 1 students was designed. In 2014/2015 school year the integrated programme for teaching science and English for Form 5 students was piloted. The teachers of English and science took part in designing the programme. However, to ensure quality CLIL lessons, the teachers need the knowledge of CLIL methodology, as well as the English language.In 2015 the teachers of English and content subjects such as maths, science and economics were organized to expand their knowledge in teaching CLIL.
