A model for preventing reading failure in grades
K-3: The big Ideas
1. Increase the quality, consistency, and reach of
instruction in every K-3 classroom
2. Conduct timely and valid assessments of reading
growth to identify struggling readers
3. Provide more intensive interventions to “catch up”
the struggling readers
The prevention of reading difficulties is a school-level
challenge

children during the year to help plan instruction
Diagnostic assessments to help provide additional
information useful for focusing and planning instruction

Screening assessments that identify children who are
lagging behind in growth of critical skills
What should we screen for?
Kindergarten – letter knowledge, phonemic awareness,
vocabulary
1st Grade–, phonemic awareness, phonics, vocabulary
2nd Grade– phonics, reading fluency, vocabulary
3rd Grade– reading fluency, vocabulary
More or less comprehensive screeners – DIBELS, TPRI,
PALS, PPVT, have information about reliability and validity

What can we progress monitor at present
Kindergarten – letter knowledge, phonemic awareness,
phonics
1st Grade–, phonemic awareness, phonics, fluency
2nd Grade– phonics, reading fluency
3rd Grade– reading fluency
Different frequencies for different groups
Whole class – three, four times a year
Students receiving interventions – more frequently
What can teachers learn from PM assessments?
Information from progress monitoring
Are the children actually learning what I am teaching?
Are the children ready to move forward in the curriculum?
Is my intervention strong enough to place the children on a
growth trajectory that ends in grade level performance by
the end of the year?

What can teachers learn from these assessments?
Information from progress monitoring
Are the children actually learning what I am teaching?
Are the children ready to move forward in the curriculum?
Is my intervention strong enough to place the children on a
growth trajectory that ends in grade level performance by
the end of the year?
Decisions to be made
Should I reteach the last unit to some of my children?
Should I move the child to a smaller group, or program more
instructional time?
Should I seek help to implement a more powerful instructional
strategy?
In order to monitor progress adequately, we need two
different kinds of information about progress
Information from curriculum embedded tests or teacher obs.
Are the children actually learning what I am teaching?
Are the children ready to move forward in the curriculum?
Information from “index” tests like the DIBELS or TPRI
Is my instruction powerful enough to place the child on a
trajectory for grade level achievement by the end of the year?

Diagnostic Testing
Purpose of diagnostic assessment-- to provide
information that is useful in planning more effective
instruction
Diagnostic tests should be given when there is a clear
expectation that they will provide new, or more
reliable, information about a child’s reading difficulties
that can be used to provide more powerful instruction.
Diagnostic testing within the rich assessment
context of screening, PM, and outcome tests
If schools are implementing screening, progress
monitoring, and outcome assessments in a reliable and
valid way, this should substantially reduce the need for
additional testing using formal diagnostic instruments.
Will the diagnostic assessment actually provide more
information, or more reliable information, about the child’s
strengths and weaknesses in the components of reading
than they already possess. If it will provide additional
information, will this new information be useful in planning
additional instruction for the child?
Diagnostic testing within the rich assessment
context of the Reading First assessment plan
Should students identified as “at risk” at the beginning of
the year automatically be administered a diagnostic test to
provide additional information to help plan instruction?
If you know a child is low in phonemic awareness, letter
knowledge, and vocabulary at the beginning of K, what
more can we reliably measure to guide instruction?
If you know a child is low in phonemic awareness, and
knowledge of the alphabetic principal, and vocabulary at
the beginning of 1st grade, what more can we reliably
measure to guide instruction?
Diagnostic testing within the rich assessment
context of the Reading First assessment plan
On the basis of the diagnostic information available from
the screening measures, interventions focused on critical
components of reading could begin immediately, rather
than waiting for additional diagnostic information
generated by diagnostic tests. The major argument for
not doing additional diagnostic testing in this case is that it
would be unlikely to add any additional information critical
to planning effective interventions, and it might delay the
process of beginning the needed interventions for these
“at risk” students.

The Florida Progress Monitoring and Reporting Network
(PMRN). Web-based data management and reporting
network
School level entry of screening, progress
monitoring, and some outcome scores
Immediate reports for teachers, principals, district

Tied to the Florida Student Information System, so
that student progress is tracked longitudinally,
and from school to school
Class Status Report for
teacher or principal
This is an example of a
first grade classroom
report for December.
The teacher can
immediately see which
of her students are at
most risk for not being at
grade level at the end of
the year, and can use
this report to group
students for targeted
instruction and support
Scores of 60% of the

Student Progress Report for teacher or principal
This report shows the progress of a third grade student in
becoming a fluent and accurate reader in third grade. At
the beginning of the year, the student was classified as
high risk on this measure, but the student received
excellent intervention, and by the end of the year, he was
performing in the low risk range.

About half our second
graders began second grade
not having met the February
1st grade benchmark in NWF
Slightly more than 20%
still hadn’t met the 1st
grade benchmark at the
end of second grade
One problem that arises from so many students
coming into 2nd grade still weak in effective, accurate
word reading strategies
Growth in fluency requires accurate practice
A major factor underlying growth in fluency for
struggling readers is how fast the number of words
they can recognize “by sight” increases
Children must read unfamiliar words with perfect
accuracy on multiple occasions before they can
become sight words
Sight vocabulary must grow very rapidly in second
grade to keep pace with normative development
Our third graders are “holding their own”
in fluency development, but they come
into third grade too far behind in the
development of fluent reading skills

What are the areas in most need of immediate

Stronger support for the growth of text reading

More powerful instruction toward mastery of the
alphabetic principle early in first grade
Creative work to develop and support stronger
interventions for struggling students in grades 1,2,
and 3 – school level must become involved
Continued efforts to expand vocabulary instructionlinked to comprehension- accessing words in
multiple contexts
Another way to think about improvements and
performance – two indices of instructional
effectiveness
Effectiveness of Core Instruction (ECI) – what percentage of
students who began the year at grade level on the
screening measures finish the year at grade level?
Effectiveness of Interventions(EI) – what percentage of
students who began the year at some level of risk on the
screening measures finish the year at grade level?

A final concluding thought….
There is no question but that “leaving no child
behind in reading” is going to be a significant
challenge…
It will involve professional development for
teachers, school reorganization, careful
assessments, and a relentless focus on the
individual needs of every child…
But, its not the most difficult thing we could be
faced with…
Consider this task for example…
