Absences

Your attendance is the biggest predictor of your success.  Attendance in the online portion of the hybrid program is registered automatically by your completion of the assignments in chronological order as listed in the course schedule. On campus attendance of every class is expected as scheduled.  The student will be allowed to miss 2 class days (exception test days) without it adversely affecting their grade and 2 lab days (exception check-off days) without it adversely affecting their grade.  Every one absence over the allotted days will result in the student’s final grade being reduced by one letter grade.  If the student is more than 15 minutes late to lecture or lab, this will constitute a tardiness. Three tardiness will count as one day absent. You are required to call the instructor prior to any absence. Failure to do so will result in an unexcused absence.

An exam missed because of an excused absence must be made up the day that the student returns to class. An exam missed because of an unexcused absence may not be made up, and the student will receive a grade of zero (0) for that exam. Pop quizzes may not be made up under any circumstances.

Late homework will receive a grade reduction of one letter grade.

All students must achieve a minimum of 78% or higher to pass this course

Cell phones shall be stored on silent in your backpack, handbag, or purse. Cell phones may be accessed during breaks.         

A student shall retain all rights to work created as part of instruction or using College District technology resources.

Hope Statement
Any student who faces challenges securing basic resources such as food, clothing, or housing and believes this may affect their performance in their course of study is urged to contact the Director of Student Resources, Dr. Deborah Cregger, for support at (817) 598-6444. Her office is on the first floor of Student Services. If the student prefers, they may contact their instructor, who can reach out on their behalf. Weatherford College also provides the Coyote Pantry. The Pantry maintains boxed and canned foods for students in need. The location of the Coyote Pantry is two blocks west of the Weatherford campus at the Baptist Student Ministry (118 E. Park Ave., Weatherford). Pantry hours are Mon-Thurs. 8:30 am-4:30 pm and Fri. 8.30 am-12:00 pm (817-599-6586).
SCANS

The Secretary’s Commission on Achieving Necessary Skills (SCANS) identified Competencies in the area of Resources, Interpersonal, Information, Systems, and Technology; and foundation skills in the areas of Basic Skills, Thinking Skills, and Personal Qualities.  This course is part of a program in which each of these Competencies and skills are integrated.  The specific SCANS Competencies that are recognized throughout this course are noted at the end of the appropriate Competencies or task listed.
