A Data Protection Impact Assessment or DPIA is a written assessment that your organisation should make to evaluate the impact of a planned processing operation. It helps you to identify the appropriate measures to address the risks, and to demonstrate compliance.

While it is always preferable to anticipate the impact of planned processing operations of your organisation by doing DPIA, it is compulsory to carry out a DPIA when the processing is likely to result in a high risk for individuals’ rights and freedoms.

Specifically, this is the case when the envisaged processing involves:

• the processing - on a large scale- of sensitive personal data or data related to criminal convictions;  
• a systematic and extensive evaluation of an individual’s personal aspects based on automated processing, including profiling, and on which decisions are based that produce legal effects concerning the individual in questions or similarly significantly affect individuals;
• systematic monitoring of a publicly accessible area on a large scale.

The EDPB has developed guidelines which list the criteria you need to take into account when assessing whether a DPIA is mandatory or not. Data protection authorities (DPAs) have also published lists of processing operations which are subject to a DPIA. In addition several DPAs have developed guides, software, or self-assessment tools to help you with your assessment.
