Frequently Asked Questions

To enlist online, you must have an AISIS account. Log on to AISIS then click the Enlist in Class link to proceed with your enlistment.

Enlistment is done by batching. Undergraduate students can only enlist on their designated batch schedule and free-for-all while graduate students can enlist during the entire online registration period.

You must first have an active account. During enlistment dates, you must be logged on during the time specified for your year level and batch.

Students on a Leave of Absence (LOA) or those Honorably Dismissed (HD) don’t have access to Aisisonline.
Students with Hold Orders are prevented from completing their enlistment, making changes in their enlistment, and proceeding to assessment. AISIS will only be available during your scheduled online enlistment period. Subjects with the status TEMPORARILY_ENLISTED means that you are currently taking the prerequisite of that subject. You will only be enlisted in your chosen class once you have passed the prerequisite. This will be done automatically when your professor has submitted your grade at the end of the current semester.
Subjects advised to be taken for the semester are indicated on your Individual Program of Study (IPS).
The following cases will result in subjects NOT being reflected on the Enlistment page:

A. A prerequisite subject has not yet been taken or passed. For example, you may have enlisted in PHILO 12 but if you failed PHILO 11, your temporary enlistment in PHILO 12 will automatically be deleted even if Ph102 is advised.
  • You may check a class’ prerequisite by checking your degree’s official curriculum in the Official Curriculum page.


  • B. The subject has already been taken. Major and Free electives must be subjects other than those already taken and must have the same units as advised.

    C. The class is tagged. Students can only enter a tagged class if they are qualified to take the class.

    D. The class is Restricted. Only pre-enlisted students are in Restricted Classes.

    E. The class is not offered for the semester even if the student has been advised.

    F. The number of units is beyond the maximum load prescribed in your curriculum.

    NOTE: For A, B, and E, please contact your home department.
    You can't modify your enlistment in a pre-enlisted class.
    Paired classes are two subjects that must be taken together. Students will be automatically enlisted/delisted for both classes.
    You can enlist for NATSCI back subjects during your respective enlistment batch schedule.
    Major Electives are defined for each curriculum. Only major electives that are offered will be reflected in online enlistment.
    If you haven't paid for your tuition nor have been assessed, you can still change your enlisted classes on your respective registration dates and during the FREE-FOR-ALL REGISTRATION. After payment, all further changes must be done through load revision.
    Unforeseen circumstances may necessitate changes in class schedules or dissolution of classes even during enlistment. This may result in an unexpected change in your schedules, such as conflicts in classes or an underload. You are advised to log on to AISIS regularly to be aware of any changes in your enlisted classes. Kindly check class schedules on aisisonline.ateneo.edu/classschedule.php as well.

    Frequently Made Mistakes

    Enlistment cannot be completed without confirmation. If you do not confirm, your slots will not be registered and you will not be officially enrolled in the classes you chose. To avoid losing your slots, click the CONFIRM button after choosing your classes. You may print your assessment form afterward.
    For First Years and Second Years, NSTP, PHYED, and INTACT are non-academic courses and as such, they are not included in the academic load. Even if you enlist for these classes, you will not be overloaded and you will be able to complete the enlistment process.
    Paying for your tuition is the last condition in order to be considered officially enrolled. Students who are officially enrolled can view their CURRENTLY ENROLLED CLASSES in AISIS.
    Please follow the batching system during the Round 1 and Round 2 online enlistment.
    Subjects such as Science subjects with both Lecture and Laboratory are considered paired subjects. Students are required to be a part of only one section for paired subjects so they must make sure that they do not enlist in different sections.
    Payments that were made without going through enlistment or assessment will not be recognized. Students must undergo the proper registration procedures. In assessment, take note that the last assessment done will be the one recorded on AISIS and on your assessment form. Make sure to double-check that your final assessment form reflects your preferred mode of payment and number of installments.
    Students are reminded to see to it that they complete the entire process*. To confirm official enrollment, please check AISIS.

    *For OAA scholars, please check facebook.com/ADMUScholarsReg for instructions and announcements.
    Students who have paid their tuition CANNOT go through online enlistment anymore. To add, change, or withdraw from sections, you will have to undergo the load revision process. To avoid this, before paying, please download/print your assessment form during your assigned online enlistment schedule, and double-check if the subjects you enlisted for are the correct number.
    Even if a student pays online, the Cashier will not recognize or validate payment beyond the deadline set for registration or load revision.
