for instance, if students by school has dupes on studentid in the same term (ie, two different kids with studentid 0000) mapvizieR will fail. perhaps write a wrapper that is...
In [summary](https://github.com/almartin82/mapvizieR/blob/e77e803978a853edb01b757e907d35b4d6651a2d/R/mapvizier_summary.R#L71) we call it `start_mean_testritscore`. In [cgp prep](https://github.com/almartin82/mapvizieR/blob/b262e71df77dded97c7903df69573d8e0a9a5df0/R/cgp_prep.R#L539) we call it `start_mean_rit'. Given that we're talking about the same calculation, we should probably pick one or the other. @chrishaid...
 if there are any retained students in the data frame, summary() generates two rows for spring to spring - one with the main cohort, and one with the retained...
NWEA doesn't provide formal norms for spring to winter, but I'm reasonably certain we could back into these expectations by looking at some combination of spring-spring, fall-spring, and fall-winter.
@chrishaid I am looking over the codebase right now and sometimes we call things a plot, other times we leave plot off the end. My initial thinking is that we...
This is a breaking change, so I wanted to open it up for discussion before I did it. Right now cgp_hist_plot shows a cohort trajectory against the **average student percentile...
against known growth figures calculated by NWEA. might be related to #251, it feels like there's bad matching happening with the new norms?
seems like it isn't matching on season?! 
would be a helpful visual for some presentations
probably by looking up some of the norms against a norms table. then we could store that in some sort of metadata slot on the mapvizieR object. not sure exactly...
