  We present here the results of the analysis of the $\gamma$-ray blazar, 1ES
1215+303, over a 10-year period, from 2008 to 2017, measured at high energies
(HE; 200 MeV $< E <$ 100 GeV) by the Fermi Large Area Telescope (LAT) and at
very high energies (VHE; $E >$ 100 GeV) by Fermi-LAT and VERITAS. This is the
longest temporal study of this high-frequency-peaked BL Lac object (HBL) at
$\gamma$-ray energies to date. The spectrum follows a log parabola over this
time period, and its HE and VHE spectra are well-connected. Its flux is
sufficiently strong at HE to allow us to bin the Fermi-LAT data in 3-day
intervals, enabling us to investigate the temporal evolution of the flux in
unprecedented detail. Several flaring episodes were detected and evidence for
an overall trend of increasing flux over the span of the 10 years was observed.
These light curves, in addition to the spectra, are presented. This unique data
set will help us to advance our understanding of the underlying physical
processes in blazar jets.
