On application, the NSP was granted provisional membership in 1966. It was invited in 1967 to the 5th International Congress of the WCPT which took place in Melbourne, Australia. Three NSP members, Messrs Ajao, Kehinde and Mrs. Aboderin, were present at the congress where NSP was formally admitted as full member of the WCPT on 18 May 1967. Since then, members of the NSP have attended the International Congress held by the WCPT, with some occupying positions in the Executive Committee.
