Teilnehmen vs. besuchen vs. beiwohnen
The German verbs teilnehmen, besuchen, and beiwohnen can all translate to "to attend" in English, but they emphasize different aspects of being present. The correct choice depends on whether you are actively participating, acting as a student or audience member, or formally observing an official occasion.
Teilnehmen
The verb teilnehmen translates to "to take part" or "to participate". It is used when attending an event implies active involvement or engagement, such as in a business meeting, a workshop, or a sports competition. This verb must be combined with the preposition an followed by the dative case.

(He wants to attend the medical conference next week.)

(Unfortunately, we cannot attend the event due to health reasons.)
Besuchen
The verb besuchen literally translates to "to visit". However, it is the standard verb used for attending an educational institution, a class, or a public entertainment event like a concert or a festival. It implies physical presence as a guest, student, or audience member, rather than an active contributor. It takes a direct object in the accusative case.

(My oldest son attends the elementary school in our neighborhood.)

(Do you really have to attend this terribly boring lecture?)

Beiwohnen
The verb beiwohnen is a highly formal and somewhat elevated term that means to witness or to be present at an event. It is almost exclusively used for official ceremonies, court trials, or formal gatherings where the attendee acts as a passive spectator. It requires an object in the dative case without any preposition.

(The French president will personally attend the solemn ceremony.)

Summary
In summary, use teilnehmen when you want to emphasize active participation and involvement. Choose besuchen when talking about attending a school, a class, or going to an entertainment event as an audience member. Reserve the formal verb beiwohnen for official ceremonies or legal proceedings where someone is present as a passive witness or spectator.
