Differences in Screening Measures by Entry Status

Measure	LSE (n = 214)		ASE (n = 75)		HSE (n = 66)		F	d^†
Measure	M	SD	M	SD	M	SD	F	d^†
RLN	34.53	14.04	53.14	10.52	59.14	9.84	124.99^*	1.41
RLS	25.14	11.32	36.00	10.79	37.65	9.44	48.79^*	0.97
WIF_N Screen	9.51	5.99	29.81	5.26	68.35	11.78	1662.87^*	3.49

Note. Low, Average, and High study entry groups were identified using Latent Class Analysis. LSE = Low Study Entry; ASE = Average Study Entry; HSE = High Study Entry; RLN = Rapid Letter Name; RLS = Rapid Letter Sound; WIF= Word Identification Fluency.
