What are the key leadership development best practices

Leadership development is the process of building the skills, judgment, and behaviors people need to lead teams effectively. For small and mid-sized companies, effective leadership development goes beyond training: define the capabilities required for the role, identify potential using structured evidence, give new leaders real decisions to own, provide regular feedback, and measure whether their behavior changes on the job.

Research on training transfer shows why this matters. A 2010 meta-analysis by Blume, Ford, Baldwin, and Huang found that transfer depends on trainee characteristics, training design, and the work environment, including support and transfer climate. For companies developing their first managers, the practical takeaway is simple: develop the leader and the environment they return to. This guide covers six practical leadership development practices for companies of roughly 50 to 200 employees without a dedicated L&D function.

TL;DR

• Define the leadership role first: Identify 3 to 6 competencies and the observable behaviors that demonstrate each one.
• Select people using structured evidence: Combine assessments, structured manager input, and evidence from real work instead of relying on promotion discussions alone.
• Change the manager's environment: Agree on what senior managers will stop doing so new leaders can actually own decisions.
• Give new leaders real responsibility: Assign a decision with clear ownership, budget, deadline, and consequences early in the program.
• Build feedback into the routine: Use short, weekly conversations focused on one observable behavior.
• Measure behavior change: compare leadership behaviors at the start and around 90 days, then track relevant team outcomes over a longer period.

What is leadership development?

Leadership development is the process of building the skills, judgment, behaviours, and knowledge required to lead people effectively. It can include training, coaching, mentoring, feedback, structured practice, and real work assignments.

The key difference is application: training introduces knowledge or skills, while leadership development gives people opportunities to apply those skills, make decisions, receive feedback, and improve their behaviour in real work situations.

Why does leadership development fail?

Leadership development often fails because new managers return to an environment that does not give them opportunities to use what they learned. Their own managers may continue making decisions for them, take back escalations, or leave no time for practice and feedback. Training can be well designed while the conditions needed for behaviour change are missing.

A second problem is selecting people for management based mainly on individual performance. Being a strong individual contributor does not automatically demonstrate skills such as delegation, coaching, decision-making, or conflict management. Leadership potential should therefore be assessed against the requirements of the management role itself.

6 best practices for leadership development

The most practical leadership development practices are to define the role, use structured evidence to identify potential, change the environment around new leaders, give them real decisions to own, provide frequent feedback, protect development time, and keep the program small enough to coach effectively.

These practices can be implemented by a small or mid-sized company without a dedicated l&d team.

1. Start from the role, not the course

Define the leadership role before choosing a development program. Identify 3 to 6 competencies the role requires, describe what strong performance looks like for each one, and specify the evidence that would demonstrate the competency.

For example, if delegation is a required competency, define observable behaviours such as assigning clear ownership, setting expectations, following up, and avoiding unnecessary take-back of work. A useful competency-to-evidence matrix connects each competency to evidence that managers can actually observe and score.

The test of a useful competency framework is consistency: two managers should be able to use the definitions and reach broadly similar conclusions about the same person.

2. Develop the environment, not only the leader

Change the environment around a new leader before the development program starts. Agree with the participant's manager which decisions, meetings, and escalations the new leader will own and which behaviours the manager will stop doing.

For example, the manager might stop approving routine decisions below an agreed threshold, attending meetings the new leader should run, or taking escalations directly from the team. Write these commitments down with a start date and review them during the program.

Leadership development is more likely to transfer into daily work when the workplace provides opportunities and support to use the new skills.

3. Hand over a real decision early

Give each participant a real decision to own within the first month, with a clear budget, deadline, scope, and consequence. Hiring for their own team is one option, but a vendor decision, process change, or customer-impacting decision can work too.

Real assignments provide evidence of how someone applies leadership skills when the outcome matters. Simulations and role plays are still useful for practising difficult situations, but they should complement rather than replace opportunities to make decisions in real work.

4. Make feedback weekly, short and specific

A 30-minute weekly conversation on one behavior beats a quarterly review of nine. Keep it to what was observed and what to try next, and have the participant write the note rather than the manager, which forces them to say what they heard. The same discipline that makes constructive feedback to candidates land applies internally: specific, behavioral, soon after the event.

5. Protect the time on the calendar

Schedule leadership development time rather than expecting it to happen alongside an unchanged workload. Block time for coaching, practice, reflection, and development assignments and treat those commitments as part of the participant's work.

For a small team, this may mean removing one existing meeting or responsibility from each participant. The goal is not to create more work. It is to create enough capacity for a new manager to practise skills that were not required in their previous role.

6. Keep the cohort small enough to coach

Start with a cohort small enough for each participant to receive meaningful feedback and practice leadership skills during the program. Six to ten participants over 12 weeks is a practical starting point for many small companies, but the right size depends on facilitator capacity and the amount of individual coaching available.

A larger cohort can still deliver useful training, but it becomes harder to provide individual feedback and connect learning to each participant's work. If coaching is the goal, design the group around the attention the facilitator can realistically provide.

Pro tip: Before you buy any program, ask the vendor what their participants' managers are required to do differently. If the answer is nothing, the program is being sold to you as a course and will be judged by you as a transformation, and both sides will be disappointed.

What follows are the same six practices against the default behavior they replace.

Is a leadership assessment a selection test?

An assessment used to decide who gets promoted can be considered an employment selection procedure in the united states. That means companies should treat assessments used for promotion differently from assessments used only for employee development.

The EEOC's guidance on selection procedures is explicit that employers use tests and other selection procedures to screen applicants for hire and employees for promotion. Title VII prohibits neutral procedures that have the effect of disproportionately excluding people on protected grounds where the procedure is not job-related and consistent with business necessity, and the Uniform Guidelines, adopted in 1978, set out three recognised routes to showing job-relatedness, known as test validation.

Practically, for a small company: keep the competency definitions tied to the actual work, keep records of scores and decisions, check whether your pass rates differ sharply across groups, and be able to explain why each measure relates to the job. A psychometric test used for development conversations carries a different risk profile from the same test used to gate a promotion, and teams buy one and use it as the other without noticing the change. Jurisdictions outside the US regulate the same ground under their own frameworks, so check local law rather than assuming this one transfers.

How do you measure leadership development ROI?

How do you measure leadership development ROI?

Measure leadership development ROI by tracking behaviour change first, relevant business outcomes second, and participant satisfaction as a supporting measure. Start with the leadership competencies defined for the role, measure them at the beginning of the program and again around 90 days, then track one or two business metrics the leader can genuinely influence.

For example, a company could measure delegation, decision-making, and coaching behaviour alongside team retention, customer escalations, delivery performance, or time to fill roles. Do not treat an improvement in a team metric as proof that the development program caused it because other business factors can influence the result.

Pair the behavioural rating with the key performance indicators the team already reports, rather than inventing a parallel set.

Use structured assessments to support leadership decisions

Leadership development does not require an assessment platform, but structured assessment tools can make it easier to evaluate the same competencies consistently across multiple people. They are particularly useful when a company needs to combine assessment results, reviewer input, and reporting in one process.

Testlify provides cognitive, personality, and role-based assessments, along with development and 360 feedback reports. These tools can support the evidence-gathering stage of leadership development while keeping the final promotion or development decision with the organization's managers.

When evaluating leadership assessment software, look for clear competency mapping, relevant assessment content, transparent scoring, useful reporting, and flexibility in how reviewers contribute evidence.

If you want to see how the scoring and reports work on a real role, book a demo, or read how teams identify and assess potential leaders and how to go about choosing a leadership skills assessment.
