I am confused about the correct preposition to use before achieving in this sentence:
Tracking service delivery is critical in achieving the goals of the health program.
I feel "critical for achieving" or "cricial to achieving" sounds better.

This question appears to be off-topic. The users who voted to close gave this specific reason:
"Critical to" is usually apt when it preceds a noun
For e.g. critical to the Health Program Certification
"Critical for" is usually apt when "joining" parts
For e.g. Studying is critical for him to gain good grades in his school
"Critical in" usually preceds a verb . This is the example you have used
I find all three acceptable, to the degree that I don't know which of the three I would use myself.
