Advanced IPEDS Dataset Cutting Tool (DCT) http://www.nces.ed.gov/ipedspas
DCT SESSION AGENDA: • Brief overview of IPEDS survey system and Peer Tool • The purpose of the DCT • The structure and features of the DCT • How to downloaddata from the DCT
Data Source:IPEDS SURVEY SYSTEM7 Survey Components • Institutional Features & Pre-Enrollment: • 1. Institutional Characteristics (IC) • Enrolled Student Information: • 2. Enrollment (EF) • 3. Completions (C) • 4. Graduation Rates (GRS) • 5. Student Financial Aid (SFA) • Institutional Finance & Staffing: • 6. Finance (F) • 7. Human Resources (HR: EAP, S, SA)
TWO “SIDES” OF THE PEER TOOL Peer Analysis System (PAS) Dataset Cutting Tool (DCT)
Dataset Cutting Tool (DCT) For one data year: • download entire IPEDS data files • Custom-build large datasets, selecting mix of schools, surveys, variables • Download datasets for analysis off-line using Excel, SPSS, SAS, or STATA • Peer Analysis System (PAS) With selected schools & variables: • rank schools by variable • calculate new variables • create standard and custom reports • View/download data, reports, graphs
DCT Options • CreateacustomizedIPEDS datasetof selected variables from one or more survey components • Download entire IPEDS survey data files Both options provide dictionary & syntax for importing data into SAS, SPSS, or STATA
Before using DCT, you also need to know about: • IPEDS Data Collection Calendar • Collection Year vs Data Year • Structure of IPEDS Data Files
View Data By? • Collection year:academic year in which the data are collected by IPEDS; i.e., IPEDS collection cycle: fall, winter, spring 2005-2006 • Data year:year of the data regardless of when they are collected by IPEDS
Collection Year vs Data Year • Fall Enrollment • Enrollment:same collection & data yr. • 12-month Headcount & Instructional Activity:prior academic year data • Inst. Characteristics & Human Resources • Same collection and data year • Completions; Student Financial Aid; Institutional Finance; Graduation Rates • Data year prior to collection year
Structure of IPEDS Datafiles • IPEDS survey data are stored as either: • Single-record files with one line of data per institution (e.g., IC; F; GRS before 2002; SFA; SA before 2001) • Multi-record files (hierarchical files) with several lines of data per institution (e.g., EF; C; HR; GRS after 2001; SA after 1999)
Single-Record File DCT merges data selected from single-record surveys into a single output file
Multi-Record File DCT merges data from multi-record surveys into separate output files for each survey
Multi-Record Files are Hierarchical Qualifying Variables:Student Level Full-time Undergraduate Full-time Graduate VariableRace/ Gender Asian Male Asian Female Asian Male Asian Female Qualifying Variables must be selected first
User-Support for DCT: • Introduction • Tutorial • Navigation Buttons on each page • Variable Label Description Links • Session Summary • Data Dictionary • Syntax for importing data into statistical software
Research Question to DemonstrateCreating a Custom Dataset In fall 2004, what was the percentage of undergrads represented in the GRS cohort and what types of aid did first-time undergrads receive at CCs in KY, MI, Ohio and PA?
Entering the DCT http://nces.ed.gov/ipedspas/
Use an institution’s 6-digit IPEDS Unit ID for User ID and Password
PAS / DCT Selection Once you have selected an access level and if necessary logged in you must choose between the dataset cutting tool or the Peer Analysis System.
3 Steps for Creating a Custom Dataset: • Select the schoolsfor which you want data • Choose the yearof data you need • Select variablesfrom one or more survey components
Criteria for Schools (this question) • Geographic Region:Any • State or Outlying Area:Kentucky, Michigan, Ohio and Pennsylvania • Degree-Granting:Degree-Granting • Type of Institution:Public 2-year • Carnegie Classification:Any • Miscellaneous: None
Other ways to select schools: Copy & Paste a comma separated list of Unit IDs (created in text editor e.g., Notepad, Word) 222178,222497,222567,222576, 222822,222832,222938,222983, 223001,223117,223214,223223, 223232,223320,223427,223463, 223524,223773,223816,223898 Upload a comparison list created in the Peer Analysis System, e.g.: inst128422357.uid HINT: Make sure your focus institution’s ID is included
List of surveys available for data year ’04 (2004-05). Select Surveys IC, EF, & SFA and Continue
Select sections from: IC - Directory information EF - Total Entering FreshmenSFA- All student counts
Progress Summary Scroll down to select variables
Sort by Survey Order: order in which variables appear in the survey If using,Sort before Find variable
Selecting Output (Same Output Options for Each Dataset) View Online (limit 50 columns; can sort by column) CSV (limit 100 columns; will download with value and variable labels
Downloading Custom Dataset Files • Create Subdirectory/Folder to receive DCT output, e.g., “C:\DCT” • (2) Select output from drop-down list, one at a time, and save in subdirectory • (3) UseDCT BackButton to return to output page to get each file • (4) Download data file, readprogram(syntax), & dictionary
CSV download for use with spreadsheet program Click on link to download file
