Growth Model for District “X”

Why Use Growth Models?Showing progress over time is a more fair way of evaluatingIt is not just a “snap shot” in time

Model Choices….

Average Growth Model Advantages:

Sliding scale score showing progress for students over time (older students have higher score than younger)

Most reliable model because of this sliding scale Disadvantages:

Student demographics and other data are not taken into consideration in averaging scores

Model Choices

Value-Added Model Advantages

Takes into consideration student characteristics Identifies not only progress made but the extent in

which schools, community and parents have contributed

Disadvantages: Requires substantial resources Because of “assumptions” and “estimates” there is

built in error

ISBE RecommendationsRecommendationsUsing these basic tenets, the Illinois Task Force on Growth Models makes

the following recommendations. They are listed under four major categories:

I. Growth Model Development• Provide support at the state level to research, develop algorithms and report

growth model data to school/districts.• Use a state algorithm that provides schools/districts with state average growth

o Over timeo For subgroupso For similar schools

• Provide resources for the Illinois State Board of Education to produce growth model reporting to schools.

• Consider how formative assessments can be used at the state level.• Consider how growth can be used to recognize the progress and gains of

schools in status.

ISBE Recommendations

II. Research• Support local and state wide pilots using growth models including

alternative schools. Use the results to help determine next steps and policy decisions.

• Research the impact of growth models on schools, districts and the state. Include the challenges and successes as well as the unintended consequences. Provide more study on how mobility impacts student improvement.

• Study and implement ways that growth model data could be used to support school improvement work.

• Study and implement ways that growth model data could be used for schools in status.

ISBE Recommendations

III. Support to Schools and Districts:• Provide resources for professional development in

data literacy.• Provide funding for every district to be registered on

the Interactive Illinois Report Card so they can easily access and analyze individual student data.

• Fund optional local benchmark assessments including the Explore/Plan for high schools.

• Integrate school improvement activities to include curriculum/instruction and assessment AND professional development.

ISBE Recommendations

IV. Alternative Schools: Illinois needs an alternative school accountability model that is

consistent with mandates, reliable/valid across alternative schools, feasible at the local level and provides a fair method of accountability for students and schools serving this vulnerable student population group.

It is recommended that state lawmakers consider requiring school districts that have alternative schools to annually evaluate such schools. Such an accountability mandate should include “value-added” assessments to acknowledge/reward academic progress of students who begin far behind and are not yet achieving to the standards measured by state tests. Student Performance data from such evaluations could be supplemental accountability information to AYP and be back-up accountability information when there is insufficient test data to report to adequately evaluate AYP

Possible Questions @ Board Meeting

Does the Growth Model truly improve student ability to grade level knowledge, which NCLB requires by 2014?

How much will this effect the district financially and in personnel?

Is this the most beneficial manner to attain AYP while still appropriately serving our students?

How would we compare scores regionally, state-wide and nationally?

Current Practice-Status Model

Status models are “one-look-in-time” approach to evaluating school performance.

A snapshot Progress is defined by students achieving at

a proficient level at a point in time.

“What is a Growth Model?”

A Growth Model is a system that tracks students over of a period of time.

Shows a students grade equivalent, or similar measure, to see if each student makes a years worth of growth in a years worth of time.

“Why the change?”

Our goal, as educators, as a board, is to help students improve throughout their years of schooling

Status models do not capture student growth over time.

Information is more effective to determine how students, classrooms, schools, and districts are performing.

Questions

How would implementing a growth model truly benefit students?

How does the growth model fit into NCLB? What impact would a growth model have on

curriculum?

We currently use the state mandated status model to determine AYP.

Status model is a snapshot approach to evaluating school performance, this model typically uses proficiency.

Disadvantages: Scores compare a given grade in one year to

the same given grade of the next year. It does not track that individual cohorts progress.

It does not provide teachers with valid target skills that are specific to the current students.

Reasons to change

A growth model refers to looking at student performance over time.

There are two types of growth models

1. Average growth.

2. Value added.

Both are very similar and both look at individual student performance from year to year.

Advantages of growth models Gives credit to school and students for progress

made. Compares same students regardless of student

mobility. Eliminates significant gains and dangerous dips. Identifies changes due to school curriculum, or

teacher effectiveness. Allows states to recognize movement towards

their proficiency even though cut scores are not met.

At Present: Status Model

Snapshot of a sub-group or school’s level of student proficiency at one point in time

Future: Growth Model

Measures progress by tracking test score

of a student group from one year to the next

to determine progress made.

Advantages

Allows credit for student progress made regardless of distance from set target point.

Aids in determining the effectiveness of particular teaching practices or programs.

Serves as the foundation for an accountability system at building level and of individual educators.

Disadvantages

Do not inherently have a universal goal such as achieving at a proficient level.

Will add significantly to the size and scope of the state accountability system.

NCLB does not allow growth to be used to calculate AYP.

Could inappropriately place blame on teachers, programs, or schools.

Recommendations

The growth model should be used as a supplement to the current status model.

District must recognize both progress and lack thereof.

District needs to provide resources to allow the school to fund optional local benchmark assessments, registration on the IIRC and for professional development in data literacy.

Why Use a Growth Model?

Gives the district a method for looking at student performance.

We choose the Value-Added Growth Model approach to appeal to student

performance. Isolates the impact of instruction on

student learning, it provides detailed information at the classroom level.

It identifies contributers that are involved in student

performance.

Provides new way to identify learning.e.g.-looks at student progress data from year to

year.Takes into consideration student’s background criteria.

e.g.-rich/poor, race, gender, IEP.Teacher effectiveness

Why choose Value-Added Approach

It identifies contributors that are involved in student performance.

Addressable Issues

Identifying Achievement Gaps 5 student characteristics Socioeconomic status, single parent families,

lack of parenting, lack of money for supplies, no positive reinforcement, possible interventions.

Measuring Impact

The best part of this approach is its ability to measure the teacher and school effectiveness and the resulting potential for increased student achievement.

Implements sophisticated statistical formulas that are intended to isolate non-educational factors such as student’s financial status and demographics.

e.g.-poor, parental involvement, etc.

Likely Impact

Helps educators target ways to improve instructions.

Alternative measure to help schools meet NCLB and AYP guidelines.

Teacher Accountability

Holds teachers accountable for student achievement.
