Legality Study allowance

Stichting Inlichtingenbureau

By law, municipalities have the task of ensuring that the study grant is given in a correct manner. Stichting Inlichtingenbureau (IB)* helps municipalities do this. We do this by comparing data from different organisations. With the results of this comparison, the municipality can check whether someone is entitled to a study allowance according to the rules.

Responsible use

Goal and impact

The IB lets municipalities know if anything changes in the situation of students receiving study allowance. Such a change may affect the amount or entitlement to the benefit. The municipality then receives a signal so that it can check whether this information was already known. If not, the municipality may decide to take action.

For each test, the minimum data required is determined. It concerns the following data:

Test for study financing or the Education Contribution and School Costs Act (WTOS)

• Data from DUO on whether or not someone receives study financing or WTOS (WTOS: an allowance for parents or guardians of pupils in secondary education and secondary special education, to help pay the costs of education).

Work test

• Data from the UWV Policy Administration on income from employment.

Test for Wajong

• Data from the UWV Policy Administration on income from a Wajong benefit.

Test on traineeship allowance above the standard

• Data from the UWV-Polisadministratie on income from internships (recognisable by a special code for interns).

Considerations

An algorithm is used to pass on data only from students supplied by the municipality who:

• receive a study allowance,

and

• in whom something has changed that may affect the study grant.

This protects citizens' privacy. An advantage of this algorithm is that it works much faster than when someone does it by hand. This saves a lot of time for municipal employees. Also, fewer mistakes are made this way.

Human intervention

For the IB itself, this algorithm does not involve human intervention. The algorithm executes rules devised by humans and is not 'self-learning'.

However, the IB does ensure that the processing process has been done properly.

The municipality decides whether and how to deal with a change.

Risk management

Citizen privacy is a major concern. That is why we periodically check whether there are risks and what can be done about them. This is called privacy impact assessment (PIA).
