WASHINGTON - When educational leaders look at ways to make Catholic schools more affordable, they are happy about some of the positive steps that have been made but fully aware that there is still a lot to do.

During a recent conference at The Catholic University of America, a group of panelists focused particularly on the status of tuition tax credits and how they have enabled students who would normally not be able to afford Catholic schools to attend them.

Currently, there are 11 school voucher programs in the United States and nine scholarship tax-credit programs. Some states have more than one program.
