Unusual Features of Program

• No Qualifying or Comprehensive Exams
• Students are admitted directly to PhD program
• Very selective admissions
• Believe that courses are more useful than exams
• Exams are an unreliable measure of understanding
• Working on labs and projects more effective than
  reading a lot of books and papers
• Have not found qualifying exams serve intended
  role
• Is student qualified to pursue a PhD?
• Student Progress Monitored Closely
• Students assigned advisors after brief
  Immigration course
• Advisor serves as mentor
• All students reviewed 2X/year in Black Friday
  meetings
• Student progress is collective responsibility of
  entire faculty

IT Workforce Issues

• US IT industry is still going strong

8
US IT Workforce Supply

• Perceptions
• IT jobs are moving offshore
• IT jobs are not exciting

9
Issues

• If Undergraduate Enrollments Continue to Decline
  
• Supply of U.S. graduate students will be limited
• Will need to attract more non-U.S. students
• Need for U.S. computer science faculty will
  decline
• Hiring for academic jobs will decrease
• But, will still have strong demand for PhDs from
  industry
