Scoil lán-Ghaeilge í Gaelcholáiste Phort Láirge (GCPL) a fheidhmíonn mar mheitheal oibre ina bhfuil sé de dhulgas ar an bPríomhoide, ar an bhfoireann bhainistíochta, agus ar gach múinteoir timpeallacht táirgiúil,
tairbheach, taitneamhach agus slán a chruthú. Iarrtar ar phobal na scoile (daltaí, tuismitheoirí agus an fhoireann iomlán) an t-éiteas seo a thabhairt chucu féin agus í a fhorbairt i ngach bealach.
Gaelcholáiste Phort Láirge (GCPL) is an all Irish school that operates a co-operative working model where it is the duty of the Principal, management team and every teacher to create a beneficial, productive, enjoyable and safe environment. The school community (pupils, parents and the school staff) are asked to embrace this ethos and foster it in every way possible.
Éiteas lán-Ghaelach Caitliceach atá i bhfeidhm sa scoil ina gcuirtear béim ar labhairt na Gaeilge mar theanga nádúrtha laethúil chomh maith le luachanna na Críostaíochta i bhfeidhm. Fáilteofar roimh gach dearcadh creidimh agus neamh-chreidimh a nglacann spiorad chultúir Ghaelach an Choláiste chucu féin.
The school promotes All Irish and Catholic ethos where there is an emphasis on speaking Irish as a natural daily language and also an emphasis on promoting Christian values. The school welcomes students of all outlooks, religious and non-religious that accept the Irish cultural spirit of the school.
