French is an optional subject which may be chosen alone or with another language to Junior Cert and Leaving Cert level. Classes are taught mostly in French and there is a strong emphasis on creating a dynamic teaching environment. Students are encouraged to use the target language from the beginning.

Classroom learning is enhanced by the use of the latest technology and students are made aware of how they can use technology at home to further their learning.

All four skills of language; speaking, listening, reading and writing are worked on and assessed continuously during the six years to Leaving Cert.

Students  benefit from the presence of a French assistant in the school and from one to one tuition in preparation for oral exams. Boys have the option to participate in French debating competitions and there is an exchange programme to France available in Transition Year.

Teachers of French in Castleknock College are continually updating their skills by participating in courses and examining at the State Examinations.
