A lot of people use the term 'kerning' when they really mean 'tracking'.
Kerning is usually expressed in thousands of an em. Funny thing is, for
text headings you usually need to have tighter tracking (negative
numbers), not a looser one (positive numbers). So I guess you had better
clarify the situation with the designer.
I got all this information from James Felici's book 'The Complete Manual
of Typography'. I have found this book very useful for a newcomer to
typography like me.
