Three Tier
Instructional
Model
The Three Tier
Instructional
Model was
adopted by the
State Board of
Education (SBE
Policy IEI) on
January 21,
2005. It is
designed to meet
the needs of
every student
and consists of
three tiers of
instruction:
Tier
1: Quality
classroom
instruction
based on MS
Curriculum
Frameworks.
Tier
2: Focused
supplemental
instruction.
Tier 3:
Intensive
interventions
specifically
designed to meet
the individual
needs of
students.
If strategies at
Tiers 1 & 2 are
unsuccessful,
students must be
referred to the
Teacher Support
Team (TST). The
TST is the
problem-solving
unit responsible
for
interventions
developed at
Tier 3. Each
school must have
a Teacher
Support Team
implemented in
accordance with
the process
developed by the
Mississippi
Department of
Education.
