Definition of Statistics

Environment

1. Budget Factor (BF) - Comparative level of school budget to state average.  This factor is based on an average school budget within the state equaling 1.00 and the percentage difference moving above and below that mark.  For example, a school budget that is 50% higher than the state average will score a 1.50, a school budget that is 27% below the state average will score a 0.73.
2. Professional Development BF (PDBF) - Comparative level of professional development budget within the school to the state average.  The scale for PDBF is identical to BF but reflects only the portion of the budget that is earmarked for the professional development of faculty members.
   
3. Socioeconomic Factor (SEF) - Comparative level of average family income in the district the state average.  This factor is scored on the same scale as BF and PDBF, but the data is drawn from the census data, not the school budget.
   
4. Community Education Factor (CEF) - Comparative level of average highest degree earned in the district the state average.  This factor is a composite of three scales.  The city/district is compared to the state average for highest educational attainment as a percentage of population.  The three measures will be high school diploma, bachelor's degree, and professional degree.  These three will be placed on the 1.00 rating scale and then totaled as such: (2*HS+Bachelors+Professional)/4.  The High School diploma statistic is double to reflect the added importance of having reached that level as a minimum.
5. Staff Ratio (SR) - Ratio of teaching to non-teaching staff members in the school. This measure is intended to show the level of administrative support that may be available within a school.  The assumption is that a high level of non-teaching staff will result in less pressure on the teachers outside the classroom.  As with the rest in the Environment category, it will be measured on a 1.00 scale in comparison to the state average.
   
6. Student - Faculty Ration (SFR) - Ratio of students to teaching staff members in the school.  Measured on the same 1.00 scale as above with the basis as the state average.

 Each of the environmental factors is based on a scale starting at 0.00, with the state average being 1.00.  This means that the majority of numbers will end up somewhere near 1.00 and the sum of each factor would average 6.00.   As the environment is serving as a factor to the total equation, a number below 1.00 (the final sum is divided by 6 to show the overall average environmental factor) will increase the final teacher's score and a number above 1.00 would decrease it.  The goal of this section is to boost the statistics of a teacher working without significant school and/or community resources to assist and slightly deflate the scores of a teacher who has all of the benefits or a full budget and dedicated community.

Experience

1. Years Teaching (YT) – Number of years the teacher has spent actually teaching in the classroom.
2. Years in Related Field (YR) – Number of years the teacher has spent involved in their field outside of direct teaching (research, professional experience, etc.).
3. Courses Taught (CT) – Number of actual courses taught, not just length of time teaching them.
4. Years in Courses Taught (YCT) – YT/CT – Designed to show the amount of career time dedicated to each subject.  The supposition with this statistic is that the greater amount of time spent in each course will reflect a higher level of preparation and experience, specific to that course.

Experience is one of the most important factors for a good teacher.  No course can teach a teacher as much as one year in front of the students.  However, the experience factors are designed to be weighted against the Classroom Engagement and Academic Success areas.  This is intended to try to reflect that experience, while important, is of little importance without results.

Classroom Engagement

1. Course Drops (CD) – Percentage of students in class that drop the course after the first day.  This percentage will be simply converted to a whole number.  For example, if 6% of the students drop the class, the CD will be 6.  While some drops are appropriate, an inordinately high number is a cause for concern and should be addressed.
2. Disciplinary Referrals (DR) – Percentage of class that receives disciplinary referrals (detention, principal’s office, etc.) due to disruptive behavior in the classroom.  It is important that this number be a percentage and not a cumulative of referrals, as one bad apple should not be allowed to spoil the bunch.  However, a teacher who is giving out disciplinary referrals widely is not gaining nor keeping the respect and attention of the students.  As with CD, DR will be a conversion of a percentage to a whole number.

It is unfortunate that these are the only two measures of classroom engagement available and they are both negative.  Yet, without an effective method of calculating exactly how engaged students are with the lessons, these will have to do.  This area leaves the most to be pondered for future improvement and innovation.

Academic Success

1. Standardized Test Results (STR) – The average scores of the teacher’s classes on related standardized testing.  The trickiness with STR is choosing which test to base the results on.  My opinion is to go with the closest approximation available.  Most states are required to test at each grade level in each subject due to the requirements of NCLB.  Regardless of the issues that I, and many others, have with the efficacy of standardized testing, they are the best single method of measuring the amount of relevant knowledge that each student has acquired.  Until someone can design a standard method of measuring critical thinking and problem-solving within various disciplines, the standardized test will reign supreme.  STR will be displayed in the form of the environmental factors (the average test score is 1.00 with variation from the norm reflected above and below that scale).  The teacher's score will reflect his or her's class average.  This does raise the issue of different scores in different classes, and it would be worth building a slightly simplified formula to measure teachers in relation to their efficacy within specific topics.
2. Matriculation Rate (MR) – The success rate at moving students on to the next grade level at the completion of the year.  Aside from testing, the primary bar to measure a teacher's success is how many of their students pass the course.  Therefore a percentage passing rate will be multiplied by 10, making a 100% pass rate a 10.0 and a 78% pass rate a 7.8.
3. Preparation Rate (PR) – Percentage of students who fail the subsequent course.  Unfortunately, MR can be significantly impacted by teachers whose goal is simply to pass along students who have not actually learned the material.  To this end, it is important to measure the success of the students in the next course year.  This will show, in conjunction with the data points, the full preparation that the student received from year to year.  It is risky to measure a teacher on the subsequent teacher's influence, but a school is a community and responsibility for the students' futures must be shared by all.  Like MR, this rate will be measured on a 10.0 scale reflecting the percent matriculating on from the subsequent course.
4. College Enrollment Rate (CER) – Percentage of students who go on to enroll in post-secondary education.  Long term preparation is the ultimate goal of any teacher and any school.  This measure, also on a ten point scale, will show the first half of this academic preparation.
5. College Graduation Rate (CGR) – Percentage of students who obtain a post-secondary degree.  CGR is the second half of the measure of long-term preparation that CER starts.  It will be measured on the same 10.0 scale.

Continuing Education

1. Bachelor’s Degree (BD) – Recognition for holding a Bachelor’s degree in a related field.  Value of 1.
2. Master’s Degree (MD) – Recognition for holding a Master’s degree in a related field.  Value of 1.
3. Doctoral Degree (DD) – Recognition for holding a Doctoral degree in a related field.  Value of 1.
4. Professional Degree (PD) – Recognition for holding a Professional degree in a related field.  Value of 1.
5. Continuing Courses Taken (CCT) – Number of related courses taken, outside of degree requirements.  Value of 1 per full credit course take.

 The value of an educated teacher is high.  More time spent formally studying the subject matter typically results in higher understanding and more examples to convey knowledge to the students.  However, there is a threshold to useful knowledge.  A Bachelors degree gives the strong base of knowledge needed to be a K-12 teacher, while a Masters can help boost an area of expertise.  However, a doctorate or professional degree (JD, MD, etc.) will likely only provide details that are above the skill level of even the most ambitious of high school classes.  So, these higher degrees are weighted less in the actual formula.  What is most important is that a teacher continue to learn, so each continuing education course completed is awarded a full point.
