<p> The first of these three papers is an empirical study estimating the impact of peer academic support on university course grades. Results suggest that, on average, about twelve peer academic support sessions increase a student's course grade by approximately one full grade point, holding constant a student's academic ability and socioeconomic status. Supplemental instruction is potentially a more effective method of peer academic support than individual peer academic support sessions and low-performing students benefit more from peer academic support than high-performing students. </p><p> The second paper analyzes the educational impact of Native American tribal casino in Washington State. We empirically study the effect tribal casinos have on the dropout rate of schools located near tribal casinos. Next we examine the impact on the dropout rate from per capita payments. Since each federally recognized tribes is a sovereign nations, each tribe makes its own laws governing the payout of these payments. These payments are largely funded by casinos. In Washington State all tribes that make per capita payments put minor tribal member's payments in trust funds that are not technically accessible until the minor child turns 18. These trust funds are having an effect on the dropout rate of young Native American adults. </p><p> The third paper examines the effect of the gender of the student, tutor and professor on the duration between tutoring sessions. Results suggest that the female students have a shorter duration between tutoring sessions. The gender of the tutor or the gender of the instructor had no effect on our results however if the student and instructor were the same gender the duration between tutoring sessions shorter. This was true for both male and female students. </p>
