I remember that article being required reading in my very first semester. Those numbers, as well as being 10 years old, are also a bit misleading because they include all school psychologists, not just doctorally trained ones. Non doctorally trained school psychologists cannot work in hospitals or private practice.
Given that only 30% of school psychologist were doctorally trained in 2002, we can calculate that about 17% of doctorally listed hospitals or private practice as their main source of income 10 years ago. I would assume that the numbers would be higher today.
Regarding private practice, it's also worth noting that many doctorally trained school psychologists engage in private practice without it being their primary source of income. We get a huge amount of vacation time in the summer, and part time private practice work can provide an extremely nice boost to income.

Although only 4.3% report private practice as their primary employment setting, even fewer (1.5%) report working 32 hours or more each week in private practice (Curtis et al., 2002).
