NCAA-M: Coach leaves box...
 

Under what circumstances can a head coach leave the coaching box to go to the scorers' table? Please rule citation....

I'll find the site - but I believe the only thing they can go to the table for is to request a time out for a correcable error.

I almost right
 

Rule 10 Section 6 Art 2
A technical foul shall be assesd to the coach and all bench personel for the following infractions:
f. All bench personnel shall remain seated on the bench while the ball is live except as follows:
4. to point out at any time a scoring or timing mistake or to request a timeout to ascertain whether a correctable error needs to be rectified (rule 2-12 5-10.5)
5. to seek information from the official scorer or official timer during a timeout or an intermission.

there is more description in the Appendix III section 1 regarding bench decorum.
