Glossary of Terms

First published in 2011, the CALP Glossary is designed to facilitate a common understanding and harmonized use of terms and definitions for cash and voucher assistance (CVA). 

It should be noted that these definitions apply to the use of CVA in humanitarian programming and may not reflect how some terms are understood in other contexts or by other audiences. 

The glossary, last updated in 2023, is available in Arabic, English, French and Spanish in both an online and PDF format. 

It is also available in German and Portuguese but in a PDF format only.

Nominal Prices

The value of goods or services in terms of money, such as local currency or foreign currency. It differs from real prices in the sense that it’s not adjusted for inflation.

Non-Contributory Schemes

Non-contributory schemes are those that normally require no direct [financial] contribution from beneficiaries or their employers. All social assistance programmes are non-contributory. This is a term used in the context of social protection to distinguish them from contributory schemes that normally require a direct [financial] contribution from beneficiaries, or their employers. Social insurance schemes are contributory.
