I may have found an issue with the CIS/TDA gradient (which possibly is also present in the full TDDFT). Version is Nwchem-6.5.revision26243-src.2014-09-10 with the Parallelmpi.patch applied. Consider the following input:

TASK TDDFT GRADIENT 

A rather strange but well-behaved molecule with some frozen virtuals.

The resulting NWCHEM analytical gradient is:
    atom               coordinates                        gradient           
                 x          y          z           x          y          z

   2 Be      0.500000  -0.020000  -0.010000   -7.226557   3.004583  -6.231942
   3 H      -0.500000  -0.020000   0.690000    1.220940  -0.550613  -6.921864

By changing the task line to
TASK TDDFT GRADIENT numerical 

I obtain the NWCHEM numerical gradient:
   atom               coordinates                        gradient
                x          y          z           x          y          z
  1 Be     -0.500000  -0.020000  -0.010000    7.294946   0.808334   5.284754
  2 Be      0.500000  -0.020000  -0.010000   -7.252036   3.003535  -6.211470
  3 H      -0.500000  -0.020000   0.690000    1.211833  -0.557386  -6.885883
  4 H       0.500000   0.180000  -0.610000   -1.254743  -3.254483   7.812599


Note the deviations in the second decimal place. I would consider this high, so high in fact, that I believe to have found a bug. Calculations using ORCA confirm this.
Consider the ORCA numerical gradient:
The cartesian numerical gradient:
---------------------------------
   1   Be  :    7.292673109    0.809276482    5.284813140
   2   Be  :   -7.250520943    3.004624398   -6.211909732
   3   H   :    1.212733473   -0.558310659   -6.886530418
   4   H   :   -1.254885640   -3.255590221    7.813627010


and the analytical counterpart:
CARTESIAN GRADIENT
------------------

   1   Be  :    7.292401418    0.809317573    5.284476022
   2   Be  :   -7.250268956    3.004906532   -6.211600815
   3   H   :    1.212702264   -0.558350628   -6.886268442
   4   H   :   -1.254834726   -3.255873477    7.813393235


Concerning the settings, I am confident to have performed the freezing correctly in both programs, given that I obtain the following excitation energies:
 NWCHEM        ORCA    
 0.147882333   0.147883
 0.567416779   0.567417
 1.182899967   1.182900
 4.676393656   4.676394
 5.899078825   5.899079

In any event, the numerical vs. analytical discrepancies of NWCHEM seem high. It would be great if someone could confirm the issue.
