	Mild	Moderate/Severe	Wald F Test Statistic	p
	n = 203	n = 97
	Weighted Prevalence (95% CI)	Weighted Prevalence (95% CI)
IEP	42.2 (29.0–56.6)	75.2 (59.9–86.1)	8.41	0.004
Grade repeated	10.5 (5.9–17.9)	40.8 (23.5–60.7)	5.90	0.015

Contacted by school about problems >2 times	28.0 (19.2–39.0)	57.6 (38.3–74.8)	6.86	0.009
Child does not care about doing well in school	19.0 (12.2–28.4)	43.8 (26.8–62.5)	5.68	0.029

The analyses for “Type of school setting” and “Grade repeated except K” resulted in high RSE, so they were excluded from this table.

ns = not significant, p > 0.05. CI, confidence interval; IEP, individualized education plan; RSE, relative standard error.
