r tableN("Distribution of students by grade")

Here's how proficiency changed over time for different grades:

prof_by_grade_by_time <- wisc %>%
  mutate(grade = as.factor(grade)) %>%
  group_by(grade, year) %>%
  summarise(pct_prof = sum(proflvl %in% c("proficient", "advanced")) / sum(!is.na(proflvl)))

ggplot(prof_by_grade_by_time, aes(x = year, y = pct_prof, fill = grade)) +
  geom_bar(stat = "identity") +
  facet_grid(grade ~ .) +
  theme_tntp() +
  scale_fill_manual(values = palette_tntp("dark_blue", "medium_blue", "light_blue", "green", "gold", "medium_gray")) +
  labs(x     = "Year", 
       y     = "Percent Proficient", 
       title = "Student Proficiency Levels by Grade over Time") +
  scale_y_continuous(labels = scales::percent)
