We report the spectral lag analysis for GRB 120305A (GCN Circ. 13004)
based on the BAT data.  Using 1-ms binned light curves, the spectral lag
for the 15-25 keV to 50-100 keV bands is 2.0 +0.6/-0.9 msec, and
-2.6 +0.6/-0.4 msec for the 25-50 keV to 100-350 keV bands
for both peaks combined.  These lag values place this burst
in the short burst category.
