The group have travelled to the Italian city for a week of meetings, venue tours and to assess progress made by Naples 2019.

Timing programmess, equipment, staff, and the press and media working area are among the areas which will be inspected by the International Technical Committee.

The Committee, led by Frenchman Jean Paul Clemencon, are due to visit all competition venues, including those for volleyball, swimming, archery, judo, water polo, football, sailing, tennis artistic and rhythmic gymnastics.

Technical delegates, directly designated from the National Sports Federations, will join the Committee and Naples 2019 officials during the week.

"National Federations will be a huge part of the organisation and will support the Organising Committee in all the sports aspects connected to the event," a statement from FISU read.

"Fifteen months left from the beginning of the event, the collaboration between the Organising Committee and FISU strengthens."

The International Technical Committee visit comes after FISU expressed their satisfaction last month at ongoing preparations for the event.

A FISU delegation completed an inspection in what was described as an "intense and productive week" by Naples 2019 organisers.

Naples was officially confirmed as the host in May 2016 following a reopened bidding process after Brasilia withdrew in January 2015.

The Brazilian capital was unable to meet financial commitments, leaving the Italian city with a tight time-frame to prepare.
