ACER ConQuest 4

Purpose: To provide data analysis based on a comprehensive and flexible range of item response models.

ACER ConQuest 4 is a computer program for fitting both unidimensional and multidimensional item response and latent regression models. It provides data analysis based on a comprehensive and flexible range of item response models (IRM), allowing examination of the properties of performance assessments, traditional assessments and rating scales. ACER ConQuest 4 also offers wider measurement and research community analysis procedures based on the most up-to-date psychometric methods of multifaceted item response models, multidimensional item response models, latent regression models and drawing plausible values

 

Features:

The ACER ConQuest Version 4 software includes:

  • Estimation of the Bradley–Terry–Luce (BTL) model for pairwise comparisons
  • A choice of marginal maximum likelihood or joint maximum likelihood estimation
  • Fitting of a multidimensional and multifaceted form of Bock’s nominal response model, including its special cases, the two parameter logistic (2PL) model and generalised partial credit model
  • Direct reading of SPSS system files
  • Output of results to SPSS or EXCEL files
  • A wide array of graphical outputs, including Wright maps and Wright predicted probability maps
  • Person fit and residuals
  • Latent variable path modelling
  • Mantel-Haenszel DIF estimates

The ACER ConQuest Version 4 has the following new features:

  • Implementation of multidimensional and multifaceted Bock model and generalised partial credit model (GPCM)
  • Addition of matrix variables
  • Matrix manipulation functions: compute, forif and while commands to manipulate matrices
  • Functionality to create likelihood plots
  • Functionality to create information maps

The ACER ConQuest 4 software update includes bug fixes.
