5.0 is the highest GPA in high school. To attain this, you must pick all the honors in all courses and at all levels. 1.6 is the lowest GPA. The type of GPA you get will be determined by your school's grading system.

It depends on where you go to school. Most high schools have a 4.00 as their highest achievable GPA. Some schools have programs such as the IB (International Baccalaureate) where you can achieve a 5.00 and graduate with come college credits.
As for the lowest it would be 0.00. Tho' that would be as hard to achieve as the 5.0.
