Absolutely, if you have the full NTPS certificate in particular you are golden. Cessna was training test pilots from scratch for a while, and all the jet manufacturers in town cultivate talent from within to some degree, but none of them can afford to drop $1M to send someone to full test pilot school as long as there is any hope of finding someone who is ready made. Since most or all NTPS pilots are former military people, it is another way the government funds private industry when you think about it.
