ECLS-K:2011 Kindergarten – First Grade Public-use File


Getting started

The ECLS-K:2011 kindergarten–first grade public-use data file (NCES 2015-086) provides data at the child level for each of the 18,174 children who participated, or whose parent participated, in at least one of the two kindergarten data collections (Fall 2010 or Spring 2011). Each child record contains data from the various respondents associated with the child, weights and imputation flags, and administrative variables. This is the first public-use file released for the ECLS-K:2011 and includes data for the first four rounds of data collection (fall 2010, spring 2011, fall 2011, and spring 2012).

From this web page, users may download ECLS-K:2011 data documentation, data files, and setup files for SAS, SPSS, and STATA. In addition, files for the ECLS-K:2011 Electronic Codebook (ECB) may be downloaded from this site. The ECB allows analysts to easily examine the variables in the dataset and facilitates the creation of SAS, SPSS, or STATA files. The ECLS-K:2011 public-use data are not available on DVD.

The data collection instruments are available at http://nces.ed.gov/ecls/instruments2011.asp

Electronic Codebook

The Electronic Codebook (ECB) software allows users to identify and examine variables available in the public-use data file. The codebook view displays the available response options and frequencies for each variable. Variables that are only available in restricted-use format also appear in the ECB, but they carry values of -2 for all cases. Using the ECB, the data user can create SAS, SPSS for Windows, and Stata syntax files that can be run to generate a customized data file containing only the variables of interest.

The ECB program runs within the Windows 95®, Windows 98®, Windows 2000®, Windows XP®, Windows NT® 4.0, Windows Vista™, or Windows 7® environment on a Pentium-class or higher personal computer (PC). The ECB is not designed for use on Apple Macintosh systems, but Mac users can create a data file using the syntax files provided below.

Syntax Files

The syntax files provided here can be run in SAS, SPSS for Windows, or Stata to create a data file containing all the variables available in the complete ECLS-K:2011 kindergarten-first grade public-use data file (approximately 9,900). Users who install the ECB on their computers can create customized syntax files to generate data sets with fewer variables than are contained in the full data set in order to more efficiently analyze the data.

Users will need to edit the setup file syntax so that the directories specified in the syntax match the location of the ASCII data file on their computers. Also, the syntax files are currently set up to create and save to a directory called C:\ECLSK2011 K1PUF\. Users need to either create this directory on their machine or appropriately alter the "Save to" step in the syntax file.

ASCII Data File

The raw data are provided in an ASCII data file named childK1p.dat, which is contained in the ZIP file below. The syntax file (either created by the ECB or the full syntax file) reads in the raw data from the .dat file to create a data file for analysis. Users should not access or modify the ASCII data file directly, as any changes made to the file will alter the raw data obtained during data collection.

Reading in data from the ASCII data file
The syntax files contain an input statement indicating where the ASCII data file is located on your computer. For example, in SPSS this statement is as follows:

FILE HANDLE FHAND /NAME='D:\childK1p.dat' /LRECL=5008.

The location of the childK1p.dat file in this input statement must match the location on your computer where you save the file. If the location does not match, the statistical software package being used will produce an error.

How to get started

From this web site, users may download data documentation, data files, and setup files for SAS, SPSS, and STATA.

Researchers wishing to obtain a disc with the data and software that supports searching through the available variables can order a free copy of the ECLS-K 1998-99 DVD. In addition to the material that can be downloaded directly from the web site, the DVD contains the ECLS-K Electronic Codebook (ECB). The ECB allows analysts to easily examine the variables in each of the ECLS-K datasets and facilitates the creation of SAS, SPSS, or STATA files.

There is an error in the data set contained in Childk8p.zip, Childk8p.z01, Childk8p.z02, Childk8p.z03, Childk8p.z04, Childk8p.z05. Corrected theta scores for all cases across all years of the study can be accessed here.

Notes

Users will need to edit the setup file syntax so that the directories specified in the syntax match the directory structure and the location of data on their computers. Users may wish to create a ECLSK folder associated with their C: drive (C:/ECLSK).

The syntax files are currently set up to create and save to a directory called C:/ECLSK. Users need to either create this directory on their machine or appropriately alter the “Save to” step in the syntax file.

The child level catalog is extremely large and has been split into 6 segments. Once all 6 have been downloaded, unzipping the primary "childk8p.zip" will automatically unzip and join the other segments into one large ASCII file.
