Is zakat obligatory on an amount of 25,000 collected from Hafiz and social security salaries, allocated for continuing education and spending on the institute, and if obligatory, how much is it?

If the saved money reaches the prescribed threshold (Nisab), which is equivalent to 85 grams of gold or 595 grams of silver, and a full lunar year (Hawl) passes from the first day it reached the Nisab, then Zakat becomes obligatory on it at a rate of 2.5%. If the money falls below the Nisab during the Hawl, then no Zakat is due on it.
