My first student, Tyler, was 14 and had finished his freshman year in high school. Just before I started tutoring him, he was given the WIAT-II to assess his reading and spelling skills.

On June 20, 2006, his scores were:

Subtest	Grade Equivalent	Percentile
Word Reading	6.8	21 %ile
Pseudoword Decoding	4.6	10 %ile
Spelling	6.5	23 %ile

He received tutoring three to four times a week, for 14 months.

On August 11, 2007, after he finished all 10 levels of the Barton System, his scores on that same test were:

Subtest	Grade Equivalent	Percentile
Word Reading	> 12.9	82 %ile
Pseudoword Decoding	> 12.9	81 %ile
Spelling **	10.4	63 %ile
** He spelled 4 words correctly that were counted wrong because they were homonyms of the dictated word. If those 4 words had counted, his spelling score would have been:	> 12.9	86 %ile
