have you considered maybe a program on

quantitative psychology?

or

educational measurement?

those are usually geared towards social scientists with limited background in mathematics.

i kinda like the general requirements that my university asks for in terms of getting accepted into their MSc in Statistics. they're basically:

An introductory course in statistics, and one in probability;

A 3rd or 4th year course in statistical inference;

A 3rd or 4th year course in regression analysis;

at least 3 of the following courses: introductory stochastic processes, 4th year probability, 3rd or 4th year mathematical statistics, design of experiments;

preferably two other 3rd or 4th year courses in statistics or computer science.

if you take those as a general guide, i'm sure you're gonna end up with a good undergraduate-like background in statistics to be ready before graduate studies.
