Is it OK for a shomer torah to participate in the Chidon Hatanach for adults, being held in Israel this Chanukah, by the Ministry of Education in conjunction with the Jewish Agency.
Answer:
Yes, this is fine.
Although there might also be non-observant participants, I don’t see this as a reason to avoid participating, and on the contrary, it is an opportunity for a kiddush Hashem.
Best wishes.
