We have obtained the first spectra of central stars of proplyds. Spectra were obtained using the Hubble Space Telescope STIS with the 52 arcsec x 0.5 arcsec slit and G750L grating, giving a resolution of 790, centered at 7751A with a bandpass from 5236A to 10266A. We describe the spectrum extraction method and present the extracted spectra and spectral types for the central stars of 164-510, 171-340, and 218-354. Using their spectral classifications, we compare them with theoretical pre-MS evolutionary models.
