As puffin has mentioned, the WJIV has fewer ceiling issues, but the reliability data for the 5-year-old age-group aren't as good as for older age brackets. So you just trade one psychometric flaw for another. The SB5 also has fewer ceiling issues, but it's old. Also, sometimes examiners give the SB5 Early edition (restricted to younger items and norms) to this age group, which has massive ceiling issues, and you can't necessarily tell from the report. Another possibility is the DAS-II, which allows for out-of-level (but properly normed) testing using the school-age battery for five-year-olds. That allows for a pretty generous ceiling, as the school-age battery is designed for through age 17-11. It's on the older side, too, but not as old as the SB5. But this is the least popular of the tests I've listed, so it may not be available in your district.
I think I'd go with the DAS-II out-of-level school-age battery, if all options were available.
