Social Security was started in the Caribbean as early as 1966 when the Jamaica National Insurance was established. Efforts at establishing a Social Security program for Grenada were first started in the 1960's when workers suffered extreme financial hardships when they were no longer able to work.

In 1970, the first Social Security package was introduced to Grenada with the proclamation of the Agricultural Workers Provident Fund. Employers were required to contribute fifteen (15) cents to the fund on behalf of each worker for every day worked. Money generated through this fund was used to pay benefits to persons covered by the fund, who were primarily agricultural workers.

In the years following its establishment it was realized that the scope of coverage provided by the fund was limited and inadequate. As a result, the International Labour Organisation was contracted as part of a Caribbean-wide project to look into the establishment of a more comprehensive Social Security Program.

This resulted in the setting up of National Insurance Schemes in several countries including Grenada. The Act which brought this into force provides for an actuarial review every three years, mainly for a review and improvements of benefits paid.

The National Insurance of Grenada, Carriacou and Pettit Martinique came into force on the 4th of April 1983 by N.I.S Law 14|1983. National Insurance is equivalent to what is referred to in other countries as "Social Security". It is the protection which society provides for its members through a series of public measures against economic and social distress that would be caused by the stoppage or substantial reduction of earnings resulting from occurrences such as sickness, invalidity, childbirth, aging or death.

The law provides for the collection of contributions and payment of benefits to insured persons. Benefits paid are Sickness, Maternity, Funeral, Age, Invalidity, Survivors and Employment Injury.
