Would you like to invite an ACER ​speaker to your event?

ACER is committed to attending external events related to its field of work and competences. However, due to limited resources, the Agency needs to carefully select the events in which its staff members participate. A decision is taken based on the event in question, as well as on the availability of staff members on the date(s) of the event.

​In order for us to make an informed decision about the event at which you would like an ACER staff member to speak, we kindly ask you to fill in the speaker request form below.
