1954, from plans drawn by H. J. Slade, and built on a three and a half acre site by Pochin, the brand new £52,400 school was opened.  It was the first new school building in the town for over 50 years.  There was much debate, about the naming of the new school.  One section of the Managers preferring the name of Thomas Ellis and the other (including Ellis Williams) preferring to honour the name of the Chancellor Briscoe.  The name of the founder of the Charity School back in 1748 was finally agreed upon.
    Managers and dignitaries assembled a the old National School, and together with the children,  proceeded to the new school.  A guard to honour was formed for the Bishop of Bangor  -  Dr. J. C. Jones.  He was handed a golden key inscribed in Welsh an English by the vice-chairman of
Anglesey Education committee who was handed the key by a representative of the contractors.  The Bishop unlocked the door of the school.  Speeches were made and the school choir sang.  Three hundred guests were given a tour of the new school.  The following day the children were given a tea party.
    School trips began in 1958, with the infants going to Benllech, and the juniors going to the Lleyn Peninsula, New Brighton, Belle Vue in Manchester, and also to London.           
    Music thrived a the school throughout the years with percussion bands and recorder groups, the latter especially under the guidance of teacher Miss Mona Preston Thomas.  The school choir was trained by Mr. Ellis Williams, headmaster, and they won many first prizes in competitions.
    Mr. Williams retired in 1973, and Mr. Emyr Salisbury Jones became the new headmaster.  Mr. Selwyn Davies introduced road safety classes, football reached a high standard with Mr. Raymond Reynolds, and netball also reached a high level under Mrs. Mari Jones.  Mr. Emyr Salisbury Jones retired in 1988 after 15 years as headmaster.  He was succeeded by Mr. Richard Hugh Jones, but the position fell vacant again in 1989 to be filled by Mr. Selwyn Davies with Mr. Eryl Wyn Rowlands filling the post of deputy headmaster.  Mr. Gareth Jones succeeded Mr. Selwyn Jones in 1995.
