IPEDS (Integrated Postsecondary Education Data System) data is a vital data source for learning about colleges in the United States. As indicated in my previous articles, a good tool/program/application is very important in making a data usable.
In my previous article, I talked about how to use a program to monitoring the performance of peer institutions. In this article, I will go through the details of using the application to access IPEDS data and search for desired colleges/institutions. The process has many implications. For one, it can be used by high school graduates to search for college of interest. The same process can also be used by institution researchers in looking for potential peer institutions.
Information on the tool/program/application I used can be found at: IPEDS College Data UI and API project. The one interested for this article is: College Search - IPEDS data for High School Graduates + Researcher.
Before we begin, we need understand that when using any
dataset, it is always important to have some basic knowledge about the
industry/subject. For IPEDS, or, college/higher-education in the United
States, these can include how institutions are classified and how these
classification can change. For this article, what we need to understand
is that institution can change - control, ownership included, and when
searching them, it is important to look for them at a specific point in
time, say, year. What you learn about an institution in one year, may or
may not be hold for other years.
Back to the topic, the program we are going to look at has many uses. For this article, we will concentrate on just one tab/function - the institution tab. Under the institution tab, there are five sub-tabs that each provides well defined purposes to guide user to accomplish their goals.
The first sub-tab is the 'basic' sub-tab. The most important function for this tab is to establish the year of interest. User begin by searching the database for all years that are available and, then, select the year of interest. Once the year is selected, this tab also provide simple filter to limited the scope of search. Available options are detailed to assist user to make decisions.
After the basic categorical filter been applied, quantitative filtering can be applied by moving to the measures sub-tab. In this sub-tab, users can iteratively search and select the measures/quantities that are interested to them.
Once the measures of interest were selected, the Variable sub-tab is ready. In this tab,user get a chance to further qualify the measure/quantity they selected. For example, user maybe looking a the quantity of part-time enrolled male students while the qualifying 'factor' can be students levels, like undergraduate, or graduate students. By selecting applicable qualifying options and assign a name, a 'user-measure' is created ... like part-time-under-men, part-time-men-under-plus-graduate, ... etc.
With fully defined 'user-measures', user can now set the 'quantitative filters'. By moving to the Query sub-tab and typing in things like: part-time-under-men>1000 or
part-time-under-men/part-time-men-under-plus-graduate > 0.5, user can select institutions that met those criteria.
After the execution of the Query sub-tab, institutions found are appended to UnitId sub-tab. From there, you can retrieve the basic identity information of each selected institutions.
Once institutions were decided, user can use other major tabs to retrieve trend data about these institution and present these data in charts. For example: College Data Search - IPEDS tool for Peer Institutions Monitoring, the video and College Data Search, a tool - Monitoring Peer Institutions, the article.
As mentioned in the video, the process is very general. It can easily apply to any measures in the IPEDS database. The process also support the combination of measures and criteria. For example, user can even check if an institution's student minority ratio is higher than faculty's minority ratio.
