Methodology

In putting together this methodology, we strived to be balanced and objective. To that end, we used only quantitative, reliable metrics with data from authoritative third parties. We do realize that no methodology is perfect, but we did our best to weed out any factors that would obviously skew the results.

Online College Inclusion Criteria


We wanted our rankings to include the most significant undergraduate degree-granting online colleges that operate nationally. Since there is no single authoritative list of online colleges on the Web — at least none that we could find — we went through multiple sources to find our initial list of colleges which we would consider for these rankings. Each source we chose is both well known and trusted. The colleges were culled from these sources from December 12, 2007 – January 10, 2008.

We then narrowed down these the list of colleges compiled from these four sources, based on the following criteria:

  1. The college must be accredited. A college must be accredited for its degrees to be respected by most employers and other legitimate higher learning institutions.

  2. The college must be listed in College Navigator. The College Navigator was commissioned by the US Department of Education to help prospective students compare higher education opportunities. We decided to exclude colleges not listed in College Navigator for two reasons: firstly, it would be impossible to rank them accurately without the trusted third-party metrics that College Navigator provides; secondly, we felt that any college not already in College Navigator was not notable and/or important enough to be included in our rankings.

  3. The college must offer more than one undergraduate degree-granting program online. We wanted to exclude specialty colleges which only offered degrees in one subject.

  4. The college, if campus-based, must offer at least 50% of its undergraduate degree-granting programs online. There are hundreds of colleges and universities nationwide that offer online programs. But very few are primarily online-based. Our rankings strive to rank only those that are primarily online-based.

The list of colleges used for our rankings is by no means comprehensive or perfect, but by using this methodology for selection we believe we included the majority of the biggest, most important, and/or most notable primarily-online colleges and universities in the United States.

The Ranking Metrics


For each metric, we ranked the colleges from 1 to 41, where 1 is the highest, or best, rank. To see the ranking for each individual metric, see the links on the left.

How We Weighted the Metrics

It was not apparent to us that any single metric was more important than any other, and further, assigning a weight to every metric would have been arbitrary. Therefore, we weighted each of the eight metrics equally.

How We Ranked the Colleges

The overall ranking for each college is simply an average of all of the metric rankings for which data was available for that college.

Adjusted Rankings

There were some metrics for which we could not find data on all of the colleges that we ranked. In these cases, we did not reward or punish the colleges for which data could not be found; instead, these particular colleges simply received no ranking for the particular metric. For the colleges for which data was available, each college received an adjusted ranking, so that the top college received a ranking of 1, but the bottom college received a ranking of 41, no matter how many colleges were actually ranked for that particular metric.

The formula used to calculate the adjusted ranking for colleges not ranked #1 is:

[(t - 1) / (d - 1)] + p

Where t equals the total number of colleges (41), d equals the number of colleges for which data was available (varied from metric to metric), and p equals the previous ranking.

Metric Qualifications

To include a particular metric in our rankings, that metric needed to be:

The Metrics We Used

Again, while this methodology may be imperfect, as is any methodology of this nature, we do want to stress that at the very least it is quantitative and objective, relying solely on hard data as opposed to subjective interpretation. We acknowledge that this certainly won't be the final say in online college rankings, and welcome any feedback at contact@oedb.org.
