We plan to repeat achievement testing for my son. My questions are which one and when?
Our reason is to collect more information. He first tested last summer at 6.7 on WISC-IV and WJ-III. There was a wide discrepancy between ability and achievement pointing to a possible LD. Analyzing subtests and additional assessments hasn't define a LD but stealth dyslexia, dyspraxia and dysgraphia are all on the table. The tester suggested we retest after a tutor, a year of development and formal educatin in first grade.
So...my questions...
1). Should I use same test so I have equal comparison? Would WIAT give me more information? Should I do both?
2). Should I test feb/march so I have information to advocate at school for next grade or wait for summer to test exactly one year after initial test? I'm not sure recommend spacing for efficacy purposes.
I'm not sure I will use same tester...I'd like to she was wonderful but very expensive ($400 for the assessment and another $400 for the debrief and numbers and if II want a written narrative report well that is another few dollars

... Groan!
