The education system in the UK is divided into four main parts, primary education, secondary education, further education and higher education. Children in the UK have to legally attend primary and secondary education which runs from about 5 years old until the student is 16 years old.

Primary school education begins in the UK at age 5 and continues until age 11, comprising key stages one and two under the UK educational system.

Some primary schools are split up into Infant and Junior levels. These are usually separate schools on the same site. The infant age range (Key Stage 1) is from age 5 to 7. The Junior age range (Key Stage 2) is from age 7 to 11.

La Educación General Básica (EGB) es el nombre que recibe el ciclo de estudios primarios obligatorios en varios países (Chile, Costa Rica y Ecuador). En algunos, como España y Argentina, se trata de un sistema educativo antiguo que ya ha sido sustituido por otros.

My low confidence level is due to the fact I don't know which country this is for.

I and II could either refer to either the level or stage. In Spain, EGB was eight years, so I and II would refer to years 1 and 2.

as with your previous question, you could leave in Spanish

I think it best to stay with a direct translation and make clear which country it refers to as it will likely be called something else in other places
