1.  International Symposium on Software Testing and Analysis (ISSTA)
    theory, academic, leading edge practitioners (see 3b in the
    periodicals section.)  Now transitioning to a summer conference that
    will alternate with ICSE.  Sponsored by ACM and ACM's SIGSOFT.

2.  International Conference on Software Engineering (ICSE).  Spring,
    world-wide.  Technical.  Primary source after ISSTA for leading edge
    results.  

3.  Quality Week (QW).  Annual, San Francisco Bay Area.  Biggest
    Conference on Testing and QA.  Typically 700+.  Many vendors.  Good
    balance between technical/theoretical and practitioners.  Very broad
    base.  Workshops.  Sponsored by Software Research Institute,
    qw@soft.com, 800-942-SOFT, 415-957-1441.

    Quality Week Europe (QWE) is held in Brussels, Belgium in November.

4.  Pacific Northwest Software Quality Conference (PNSQC).  Annual,
    Portland Oregon, October.  Definitely not a regional conference,
    despite the name.  Very broad from technical/research to
    practitioners.  A shade more academic and leading edge participation
    than quality week.  

5.  International Conference and Exposition on Testing Computer Software
    (TCS).  Less technical and more practitioner/management than Quality
    Week.  Smaller, 400+.  Workshops.  17th annual conference was June
    12-15, 2000, in Washington, D.C.  Presented in cooperation with the
    ACM SIGSoft, ASQ Software Division, IEEE Reliability Society, and
    Software Technology Support Center.  

6.  Software Testing, Analysis, and Review (STAR).  Software Quality
    Engineering.  STAR East is in Orlando in May, and STAR West is on
    the east coast in the fall.  About the same target as the
    International Conference (5) above.  Comparable level and interest.  
    Workshops.  SQE 1-800-423-8378.  

7.  QAI International Software Testing Conference.  More of a
    tutorial/workshop than a conference.  Newbie orientation.  Fall,
    Orlando, Florida.  Quality Assurance Institute, 407-363-1111.

8.  IEEE Compsac, world-wide, various locations.  Fall.  Typical IEEE
    technical conference with a substantial number of papers of direct
    interest to testing and QA.  Not as many as IEEE Software
    Engineering, though.
