I think you finally will get a correct answer if you at least tell us what is wrong with the previous suggestions we have made here

Here is another solution

select		d.tpa_id,
		case when d.it > 1 then 'High' else 'Low' end as status
from		(
			SELECT		emd.tpa_id,
					count(*) it
			from		dbo.EMPLOYER_DIVISION AS ED
			inner join	EMPLOYEE_MISC_DATA AS EMD on emd.tpa_id=ed.tpa_id and emd.empe_key=ed.division_key)
			group by	emd.tpa_id
		) d

Well, at least you could have the decency to tell us what is wrong and even when it worked for you.
