here is the offical IRS calculator to determine eligibility for EITC
note that like other tax benefits, if you CAN be claimed as a dependent (e.g. a college student) you are not eligible for EITC, even if your parents did not claim you.
there are rules about students claimsing EITC and in many cases they are not eligible (but in other cases they are), which will be evident when going through these eligiblity rules for EITC. As this is directly from the IRS website, it'll be the same rules used to review anyone's tax return.
