We report the spectral lag analysis for GRB 120229A (GCN Circ. 12997)
based on the BAT data. Using 4-ms binned light curves, the spectral lag
for the 15-25 keV to 50-100 keV bands is 0.8 +-8 msec, and 3.6 +5/-7 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.
