This study examined technical characteristics of slopes produced from two general outcome measures(GOMs)—the Naming Spelling and the Dictating Spellingtests. A total of 305 first-graders in Taiwan participated inthe study and underwent weekly assessments for 6 weeks.Six alternate forms were developed for each of the two measures to monitor young students’ learning progress ofZhu Yin Fu Hao (ZYFH). Technical characteristics of thetwo measures were examined in terms of reliability, sen-sitivity, and criterion validity for assessing student growth.Results showed that the alternate-form reliability coeffi-cients ranged from .88 to .94 (mean=.92) for the Naming Spelling test, and from .77 to .83 (mean=.80) for the Dictating Spelling test. Both tests demonstrated to besensitive for monitoring student’s learning progress by revealing a quadratic growth pattern and inter-individual differences in growth rates. The growth rates estimated from repeated Naming and Dictating Spelling tests werefound to correlate with students’ performance on the finalexam of ZYFH for lower-performing students. Results support the use of these two GOMs tests as reliable, sen-sitive, and valid measures for monitoring first-graders’learning progress of ZYFH
