Please read thoroughly:
a screening is NOT a diagnostic assessment!
PSA: if a district does not have valid diagnostic reading assessments as described by 20 USC 6368(7)c and only considers a screening tools [20 USC 6368(7)b] then the decisions for and IEP as explained in -20 USC 6368(7)c - are not being met!!
The term “diagnostic reading assessment”
means an assessment that is—
(i) valid, reliable, and based on scientifically based reading research; and
(ii) used for the purpose of—
(I) identifying a child’s specific areas of strengths and weaknesses so that the
child has learned to read by the end of grade 3;
(II) determining any difficulties that a child may have in learning to read and
the potential cause of such difficulties; and
(III) helping to determine possible reading intervention strategies and related
special needs.
The TOWRE, the CTOPP, the GORT are examples of valid diagnostic measures- more than one is needed! The WIAT is an achievement test - there is nothing wrong with an achievement test ... it's just not designed as a diagnostic test!
