Use the whole-semester total if you know it and want a projection.<\/li>\n<li>Enter the minimum attendance your school or college requires in the <strong>Required attendance<\/strong> field (75% is common; many universities use 75\u201385%).<\/li>\n<li>Read the results: your <strong>Attendance percentage<\/strong>, your <strong>Attendance status<\/strong> relative to the requirement, and how many classes you must attend in a row \u2014 or can safely skip \u2014 under <strong>Classes to attend \/ can skip<\/strong>.<\/li>\n<\/ol>\n<h2>What Is Attendance Percentage?<\/h2>\n<p>Attendance percentage is the share of classes you have attended out of all classes held, expressed as a percentage. Schools, colleges and universities use it as a measure of engagement, and many enforce a minimum threshold \u2014 commonly 75% \u2014 below which you may be barred from exams, marked as a shortage of attendance, or required to repeat the course.<\/p>\n<p>Because the percentage depends on both counts, a single absence early in the semester has a much bigger impact than the same absence later. After 10 classes, missing 2 gives 80%; after 100 classes, missing 2 gives 98%. This is why it pays to check your attendance regularly rather than only near the end of the term.<\/p>\n<p>The calculator also answers the practical question behind the number: <em>what do I need to do next?<\/em> If you are below the requirement, it tells you how many consecutive upcoming classes you must attend to reach the threshold \u2014 not just to recover the percentage you lost, but accounting for the fact that upcoming classes add to both counts. If you are above the requirement, it tells you how many classes you can still afford to miss before dropping below the threshold.<\/p>\n<h2>Assumptions, Limitations and Tips<\/h2>\n<ul>\n<li><strong>Counting method.<\/strong> The calculator assumes the standard convention: every class attended adds 1 to both attended and held counts; every skipped class adds 1 only to classes held. Some institutions count medical leave or excused absences differently \u2014 check your own rules.<\/li>\n<li><strong>Consecutive attendance.<\/strong> The \"classes to attend\" figure assumes you attend <em>every<\/em> upcoming class with no further absences. If you skip additional classes along the way, you will need more than the stated number.<\/li>\n<li><strong>The skip limit is a ceiling.<\/strong> The \"can skip\" figure assumes you skip that many classes and then attend all remaining ones. Skipping more than the stated number drops you below the requirement at that moment.<\/li>\n<li><strong>Plan with a buffer.<\/strong> If your result says you can skip, say, 6 classes, treat that as an emergency reserve. Illness, travel or scheduling conflicts are easier to absorb when you are comfortably above the threshold.<\/li>\n<li><strong>Rounding.<\/strong> The percentage is rounded to two decimal places for display. If your institution rounds differently (for example, truncating 74.99% to 74%), aim slightly above the threshold rather than exactly at it.<\/li>\n<li><strong>Per-subject attendance.<\/strong> Most institutions track attendance per subject or per course, not overall. Run the calculation separately for each subject where you are near the threshold.<\/li>\n<\/ul>\n<h2>Common Attendance Requirements<\/h2>\n<table>\n<thead>\n<tr>\n<th>Institution type<\/th>\n<th>Typical requirement<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Schools (many boards)<\/td>\n<td>75%<\/td>\n<\/tr>\n<tr>\n<td>Universities and colleges<\/td>\n<td>75\u201385%<\/td>\n<\/tr>\n<tr>\n<td>Professional and certification courses<\/td>\n<td>80\u201390%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Always confirm the exact threshold with your institution \u2014 requirements vary by board, course and even by semester, and some apply them per subject rather than overall.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enter the classes you attended, the total classes held, and your required attendance percentage.
