CPS members who have received 5 merit marks become Senior Members.  When these members receive their 20th Merit Mark, they become Life Members.  They are also awarded a special CPS flag and a 20 year plaque. Many members just keep working and have 30 or more Merit Marks. Some work for their squadrons, some go to work for the District or the National Committees but all the Merit Mark time is 'banked' and reported to Headquarters.  The Merit Mark Certificates are then sent to the home squadron in time for the Graduation Ceremonies.  They are usually presented by District Commander.
