Institutional Mission

Atlanta Technical College, a unit of the Technical College System of Georgia, provides lifelong educational opportunities and experiences through academic and innovative career preparation, service learning, and multiple program delivery modalities that lead to technical certificates, diplomas, and associate degrees and make student development and success possible in a competitive global economy

Required Technology

Participation in online courses requires reliable technology that meets current Blackboard Ultra and Respondus LockDown Browser standards.

A desktop or laptop computer running a supported operating system is required: Windows 10 or 11, macOS 11 (Big Sur) or later, or Chrome OS. Tablets and smartphones may be used to check announcements or view content; however, these devices are not reliable for completing assignments, quizzes, or exams, and some tools may not function as expected. Chromebooks may allow basic access but do not support all features or proctored testing tools.

The latest version of Google Chrome is the recommended browser for Blackboard Ultra. Browsers should be kept up to date, with cookies and pop-ups enabled for full functionality.

A stable broadband internet connection (DSL or cable recommended) is required. A wired connection is strongly advised during tests or video conferencing sessions to prevent interruptions.

Recommended software includes Microsoft 365 (available to ATC students at no cost), Adobe Acrobat Reader for viewing PDF files, and up-to-date audio and video drivers for multimedia use. Systems should maintain current antivirus protection and regular updates to ensure compatibility and security.

For best performance, browsers should be cleared of cached data regularly, and Blackboard’s Browser Checker (available on the Blackboard login page) should be used to verify system compatibility.

Blackboard

Once you have access to Blackboard you will be enrolled in the Student Learning Community Organization (SLC). The SLC offers Blackboard training and other valuable college resources.

Attendance

The educational programs at Atlanta Technical College reflect those requirements and standards that are necessary for future successful employment in business and industry. Employers expect their employees to be present and to be on time for work each and every day. Likewise, Atlanta Technical College expects each student to be present and to be on time each and every day for all classes. Absences prevent students from receiving full course benefits, disrupt orderly course progress, and diminish the quality of group interaction in class. The college considers both tardiness and early departure from class as forms of absenteeism.

Instructors have both the right and the responsibility to develop reasonable attendance expectations appropriate to the type, level, delivery method, and frequency of class meetings for their courses; communicate the expectations to students clearly via their syllabi addenda; and apply the consequences of failing to meet the expectations fairly and consistently to all enrolled students.

Instructors are responsible for determining whether work missed may be made up, and any make-up work allowed is scheduled at the discretion of instructors. Procedures for make-up work are detailed in syllabi addenda.

Documented absences for military duty, observed religious holidays, judicial proceedings in response to a subpoena, summons for jury duty, or other court-ordered process which requires the attendance of the student at the judicial proceeding are excused. Students absent from class for any reason are still responsible for all work missed. Students should enroll only in those classes that they can reasonably expect to attend on a regular basis.

Students who stop attending classes without officially withdrawing from class risk earning a final grade of F. If a student does not officially withdraw the instructor may issue a final grade of F and the last date of attendance, which will be last day that the student attended class or participated in an academically related activity.

In the event of severe weather or other emergencies, students are expected to continue participating in learning activities via Blackboard, @student.atlantatech.edu email account, or other modality.

Failure to attend class the first week may result in students being turned in as no-shows. See No-Show Policy for further information.

Course Withdrawal

WITHDRAWAL POLICY

The sole responsibility to officially withdraw from any class(es) or the College lies with the student. The effective date of withdrawal is the date the student notifies the college of the withdrawal.
Students have the privilege of dropping a course during the first three instructional days of each semester, through their BANNERWEB account, without the drop becoming a part of your permanent academic record and without it affecting your financial aid.

Please remember, any amount charged against student financial aid (PELL/Scholarships...etc.) in the bookstore will be owed back to the College.

The following criteria has been established for students who elect to withdraw after the third day of classes:

Beginning the fourth day of the term and through 60% of the term, students can withdraw from classes via their BANNERWEB account. Students who elect to withdraw during this period will receive a grade of “W” on the official academic record and will not receive a refund of applicable tuition and fees.
After the “W” (or 60%) through the end of the term (last day of class), students can withdraw from classes via their BANNERWEB account. Students who elect to withdraw during this period will receive a grade of “F” on the official academic record and will not receive a refund of applicable tuition and fees.
Students are prohibited from withdrawing from any class(es) during final exam week.

Students who choose to not withdraw from classes will be classified as abandoning the course. Abandoning a course instead of following official withdrawal procedures may result in a failing grade assigned by the instructor and financial aid adjustments to the student’s account, if applicable.

HARDSHIP WITHDRAWAL

The intent of a “Hardship Withdrawal” is to remove the negative effect of absences that are beyond the control of the student - if those absences affected the student’s ability to withdraw by the deadline or occurred after the posted withdrawal deadline.
The hardship withdrawal submission period opens after the W (or 60%) posted date. A hardship withdrawal, if approved, is defined as a withdrawal after the 60% deadline. A student may petition for a hardship withdrawal by submitting the “Hardship Withdraw Request Form” from the Office of the Registrar. Hardship withdrawals MUST be requested no later than the end of the following semester for which the withdrawal is requested.
• (e.g.- to submit a request for a Spring Semester course, the Office of the Registrar must receive the request no later than the last day of the Summer Semester).
Examples of a reason to submit a hardship withdrawal includes, but is not limited to, hospitalization of the student, death in the immediate family, or military duty. A request must include verifying documentation of the extenuating circumstances.
If a hardship withdrawal is requested/granted, it will include all classes for the given term. Only one hardship withdrawal is allowed per student while enrolled at ATC. The final decision as decided by the Office of Academic & Student Affairs regarding the hardship withdrawal is final and not subject to appeal.

Grading Scale

Grades are issued at the end of each semester. A grade of "C" or better is required for most programs in all classes for graduation. However, there are some programs that may require a “B” or better; therefore, it is recommended that students consult with their specific program advisor.

Grades	Numerical Equivalent	Grade Points
A	90-100	4
B	80-89	3
C	70-79	2
D	60-69	1
F	0-59	0

Other grades allowed by Atlanta Technical College include:

EX	Exempted by Examination	Not Computed
W	Withdrew	Not Computed (Only Given Before 60% Deadline)
TR	Transfer Credit	Not Computed (Displayed as TRA, TRB, or TRC – See Below)
AU	Audited	Not Computed
S	Satisfactory	Not Computed
U	Unsatisfactory	Not Computed
I	Incomplete*	Not Computed

*Course Requirements for removal of an incomplete must be satisfactorily completed prior to the following semester’s mid-term date.

I Indicates that student has an "incomplete" but has satisfactorily completed a substantial portion of the course work. For NON-ACADEMIC reasons beyond their control, the student has not been able to complete some specific part or amount of the work required. An "I" must be satisfactorily changed to a letter grade by the midpoint of the next semester, or it will be changed to the grade of "F" by the Office of Enrollment Services. Students must get approval from the instructor prior to the end of the semester to be eligible for an "I" grade. No credit is given and no grade points are calculated.

IP Indicates that a course continues beyond the end of the semester. An “IP” must be satisfactorily changed to a letter grade by the midpoint of the next semester, or it will be changed to the grade of “F” by the Office of Enrollment Services. No Credit is given and no grade points are calculated.

W Students who withdraw before the 60% point of the semester receive a grade of “W” Withdrew. No credit is given and no grade points are calculated.

EXE Indicates that a student has exempted a course through examination or through the articulated Tech Prep programs. Credit is given but grade points are not calculated. Instructors must submit an Exemption Form to the Office of Enrollment Services to report an exemption.

EXP Indicates the student has been awarded transfer credit though essential learning/prior learning assessment

TR Indicates that a student has been awarded transfer credit from AP. CLEP or IB examinations.

TRA, TRB, TRC Indicates that a student has been awarded transfer credit from another institution. Credit is given but no grade points are calculated. If a student earns credit for a course taken at Atlanta Technical College for which transfer credit has been awarded, then the transfer credit will be deleted from the student's record.

TRM Indicates that a student has been awarded transfer credit from their military experience.

AC Indicates articulated credit earned by students as a part of formal articulation agreements.

AU Indicates an audited course. No grade is given, no credit hours are earned and grade points are not calculated. Auditing a course must be initiated during the registration process. Approval for an audit cannot be granted after participation in classroom instruction. Instructors must submit an Audit Form to the Office of Enrollment Services to report an audit. Audited classes are not eligible for financial aid.

Z indicates students whose academic performance was affected by the COVID-19 global pandemic. A grade of Z is the functional equivalent of a grade of W; the course in which a student received a Z grade does factor into total credit hours attempted for financial aid calculations but does not affect overall GPA.
