Focus on the five reasons most often stated by schools for dropping IB.
    1) Cost
    2) Lack of student improvement with IB
    3) Less flexible than AP
    4) Lack of participation in IB classes
    5) Lack of college credit for IB

At least 20 schools drop IB in about a year.  All of them name from one to all five of these reasons for dropping IB.  Even though some people do not like the fact that IB is a United Nations sponsored programme, http://myinclinevillage.com/2010/07/16/even-jay-matthews-admits-colleges-give-more-credit-for-ap.aspx
districts never state this as a reason for dropping IB.

If you are fighting IB in your district focus on the five reasons above, NOT the UN.

Our District - It took almost two years to stop IB from being implemented.  The battle divided our quiet affluent community on the north shore of Lake Tahoe.
