Injured Spouse Allocation, can tax credits for children be allocated to a spouse with no income?

My wife and I file jointly and our refund is being taken for offset. I owe money towards a federal student loan but would have a nice tax return because of the earned income credit and the child tax credit. Can the child tax credit be allocated to my wife on form 8379? I understand the income credit being tied to my income, but is the child tax credit tied to me as well?
