Do I have to tell my parents how much money I made if they claim me as their dependent?

I'm a full-time student and my parents claim me on their taxes.  My parents didn't want me to get a job so I can concentrate on my studies.  I got a job anyways, without them knowing.  Do I have to report how much money I made to them?  Like, do they have to know how much money I earned when they file their taxes?  I made $8,000 this year
