ACER ConQuest 5 Instructor Licence (Annual) – MAC

ACER ConQuest 5 is a major version update to ACER ConQuest.

ACER ConQuest 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 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.

Discounted pricing is available on purchases of standard ACER ConQuest 5 licences for teaching. Instructor licences can be used by all students in a single course. Instructor licences are limited to one year and can be used with sample sizes up to 3000 participants. For sample sizes greater than 3000, an Extended Licence is required.

This is the MAC version of the instructor licence. You may purchase this licence once you have downloaded the installer for ConQuest 5 Installer.

Once you have purchased your ACER ConQuest licence, you will be emailed a licence key. The email will also include instructions about how to enter the key and upgrade the trial software to a full licence.

If you do not have the latest version of ConQuest or you have a new computer you may need to upgrade or re-download the installer.

Once you have reinstalled ConQuest:

• You will be able to use your existing licence key if you are reinstalling in the same year as you purchased the key.
• If you have lost your key, you will need to email us at sales@acer.org and advise us. Please include as much information about your original purchase as possible.
• You will also need to email us at sales@acer.org to obtain a new key if you are reinstalling in a year other than which you purchased your original key. Please include your old licence key in your email.

(Note: reinstalling the software does not initiate a new trial period - trials are limited to one per person. If you have already completed a 30-day trial, full use will require a licence key.)
