2054.3	Assessment
Research Question (Clear, unambiguous)	"[W]hether the child will have better outcomes when they accept preschool or any kind of early educations."  Although not stated as clearly as we would like, the basic idea is fine.  The question is whether preschool attendance has an independent affect on later educational achievement.
Relevant Literature	The articles listed are clearly directly relevant.  Of course, you would have to review all the relevant work in this area.
Causal Interpretations (clear, all parts defined, mechanisms, controls, plausible)	Again, the causal interpretation is a bit simplistic (and here, not well stated).  This is just a repetition of the research question.  Preschool might improve later educational achievement or attainment, or it might not.  Yes, but how?  Without a grasp of the possible causal mechanisms, you have a difficult time identifying the proper controls.
Data (variables, sample, comparison)	The Fragile Families data seem fine, what you would do with the GSS is unclear.  Neglects the obvious analytical issue of control variables, given that participation in preschooling is hardly a random event.
Research Value	The suggestion that the research could help parents decide on the value of preschooling is dubious, with little sense of what influences parents' decisions.  It would be more to the point that the value of preschooling is an important question for educational policy.
Overall	The general aim of the research is okay, although the presentation here is weak.  Whether the research is worth pursuing would depend both on improving the research design and on examining the literature to discern if you have anything new to offer.
